BACKGROUND

Lymphocyte Activation Gene-3, or LAG-3 (also known as CD223), is a member of the immunoglobulin supergene family, and is expressed on activated T cells (Huard et al. (1994) Immunogenetics 39:213), NK cells (Triebel et al. (1990) J. Exp. Med. 171:1393-1405), regulatory T cells (Huang et al. (2004) Immunity 21:503-513; Camisaschi et al. (2010) J Immunol. 184:6545-6551; Gagliani et al. (2013) Nat Med 19:739-746), and plasmacytoid dendritic cells (DCs) (Workman et al. (2009) J Immunol 182:1885-1891). LAG-3 is a membrane protein encoded by a gene located on chromosome 12, and is structurally and genetically related to CD4.

Similar to CD4, LAG-3 can interact with MHC class II molecules on the cell surface (Baixeras et al. (1992) J. Exp. Med. 176:327-337; Huard et al. (1996) Eur. J. Immunol. 26:1180-1186). It has been suggested that the direct binding of LAG-3 to MHC class II plays a role in down-regulating antigen-dependent stimulation of CD4⁺ T lymphocytes (Huard et al. (1994) Eur. J. Immunol. 24:3216-3221) and LAG-3 blockade has also been shown to reinvigorate CD8⁺ lymphocytes in both tumor or self-antigen (Gross et al. (2007) J Clin Invest. 117:3383-3392) and viral models (Blackburn et al. (2009) Nat. Immunol. 10:29-37). Further, the intra-cytoplasmic region of LAG-3 can interact with LAP (LAG-3-associated protein), which is a signal transduction molecule involved in the downregulation of the CD3/TCR activation pathway (Iouzalen et al. (2001) Eur. J. Immunol. 31:2885-2891). Moreover, CD4⁺CD25⁺ regulatory T cells (T_(reg)) have been shown to express LAG-3 upon activation, which contributes to the suppressor activity of T_(reg) cells (Huang, C. et al. (2004) Immunity 21:503-513). LAG-3 can also negatively regulate T cell homeostasis by T_(reg) cells in both T cell-dependent and independent mechanisms (Workman, C. J. and Vignali, D. A. (2005) J. Immunol. 174:688-695).

Given the importance of LAG-3 in downregulating an immune response, the need exists for developing novel agents that modulate its activity to activate the immune system. Such agents can be used, e.g., for cancer immunotherapy and treatment of other conditions, such as chronic infection.

SUMMARY

Disclosed herein, at least in part, are methods and compositions comprising a combination of two, three or more therapeutic agents chosen from one, two, or all of the following categories (i)-(iii): (i) an agent that enhances antigen presentation (e.g., tumor antigen presentation); (ii) an agent that enhances an effector cell response (e.g., B cell and/or T cell activation and/or mobilization); or (iii) an agent that decreases tumor immunosuppression. In some embodiments, the combination includes an inhibitor of Lymphocyte Activation Gene-3 (LAG-3) (e.g., an anti-LAG-3 antibody molecule as described herein).

Without wishing to be bound by theory, it is believed that therapeutic approaches that enhance anti-tumor immunity work more effectively when the immune response is optimized by targeting multiple components at one or more stages of an immune response, e.g., an anti-tumor immune response. For example, approaches that enhance antigen presentation, e.g., by activation and/or maturation of dendritic cells, combined with approaches that enhance cellular and humoral immune responses (e.g., by stimulating, e.g., disinhibiting, phagocytes and/or tumor infiltrating lymphocytes (e.g., NK cells and T cells)), while blocking tumor immunosuppressive signaling (e.g., by increasing macrophage polarization, increasing T_(reg) depletion and/or decreasing myeloid-derived suppressive cells (MDSCs)) can result in a more effective and/or prolonged therapeutic response. Accordingly, disclosed herein are combination therapies that optimize one, two, or all of: (i) antigen presentation, e.g., increasing antigen presentation (e.g., by enhancing one or more of dendritic cell activity or maturation, antigen uptake, or antigen processing); (ii) effector cell response, e.g., increasing effector cell response (e.g., enhancing B cell and/or T cell activation and/or mobilization, e.g., in the lymph node); or (iii) tumor immunosuppression, e.g., decreasing tumor immunosuppression (e.g., increasing T cell infiltration and tumor cell killing). The combinations described herein can provide a superior beneficial effect, e.g., in the treatment of a disorder, such as an enhanced anti-cancer effect, reduced toxicity and/or reduced side effects, compared to monotherapy administration of the therapeutic agents in the combination. For example, one or more of the therapeutic agents in the combination can be administered at a lower dosage, or for a shorter period of administration, than would be required to achieve the same therapeutic effect compared to the monotherapy administration. Thus, compositions and methods for treating cancer and other immune disorders using the aforesaid combination therapies are disclosed.

Accordingly, in one aspect, the invention features a method of treating (e.g., inhibiting, reducing, ameliorating, or preventing) a disorder, e.g., a hyperproliferative condition or disorder (e.g., a cancer) in a subject. The method includes administering to the subject a combination of two, three or more therapeutic agents chosen from one, two or all of the following categories (i)-(iii): (i) an agent that enhances antigen (e.g., tumor antigen) presentation; (ii) an agent that enhances an effector cell response (e.g., B cell and/or T cell activation and/or mobilization); or (iii) an agent that decreases tumor immunosuppression, thereby treating the disorder, e.g., the hyperproliferative condition or disorder (e.g., the cancer). In some embodiments, the combination includes a LAG-3 inhibitor (e.g., an anti-LAG-3 antibody molecule as described herein). The cancer treated can be, e.g., a cancer described herein, such as a lung cancer, a melanoma, a renal cancer, a liver cancer, a myeloma, a prostate cancer, a breast cancer, a head and neck cancer, a colorectal cancer, a pancreatic cancer, a hematological cancer, a non-Hogdkin's lymphoma, or a leukemia, or a metastatic lesion of the cancer.

In another aspect, the invention features a method of reducing an activity (e.g., growth, survival, or viability, or all), of a hyperproliferative (e.g., a cancer) cell. The method includes contacting the cell with a combination of two, three or more therapeutic agents chosen from one, two or all of the following categories (i)-(iii): (i) an agent that enhances antigen (e.g., tumor antigen) presentation; (ii) an agent that enhances an effector cell response (e.g., B cell and/or T cell activation and/or mobilization); or (iii) an agent that decreases tumor immunosuppression, thereby reducing an activity in the hyperproliferative cell. In some embodiments, the combination includes a LAG-3 inhibitor (e.g., an anti-LAG-3 antibody molecule as described herein). The method can be performed in a subject, e.g., as part of a therapeutic protocol. The cancer cell can be, e.g., a cell from a cancer described herein, such as a lung cancer, a melanoma, a renal cancer, a liver cancer, a myeloma, a prostate cancer, a breast cancer, a head and neck cancer, a colorectal cancer, a pancreatic cancer, a hematological cancer, a non-Hogdkin's lymphoma, or a leukemia, or a metastatic lesion of the cancer.

In certain embodiments of the methods disclosed herein, the method further includes determining the level of an immune cell (e.g., a T cell) infiltrate (e.g., the level of tumor infiltrating lymphocytes (TIL)) in the subject. In one embodiment, the level of the immune cell infiltrate is determined in vivo, e.g., non-invasively (e.g., by detecting an antibody to a T cell marker detectably labeled using a suitable imaging technique, e.g., positron emission tomography (PET) scan). In other embodiments, the level of the immune cell infiltrate is determined in a sample (e.g., a tumor biopsy) acquired from the subject (e.g., using immunohistochemical techniques). In embodiments, responsive to a low level of, or no detectable, tumor infiltrate in the subject, one or more agents of categories (i) or (ii), or both (i) and (ii), is/are administered. In other embodiments, responsive to a detectable level, or an elevated level, of tumor infiltrate in the subject, one or more agents of category (iii) is/are administered. The detection steps can also be used, e.g., to monitor the effectiveness of a therapeutic agent described herein. For example, the detection step can be used to monitor the effectiveness of therapeutic agents of categories (i), (ii) and/or (iii).

In certain embodiments, the combination includes a combination of therapeutic agents as provided in the section entitled “Exemplary Combinations of Antigen-Presentation Combinations, Effector Cell Combinations and Anti-tumor Immunosuppression Combinations” provided in the Detailed Description.

The combinations disclosed herein can be administered together in a single composition or administered separately in two or more different compositions, e.g., compositions or dosage forms as described herein. The administration of the therapeutic agents can be in any order. The first agent and the additional agents (e.g., second, third agents) can be administered via the same administration route or via different administration routes. For example, a first therapeutic agent can be administered concurrently with, prior to, or subsequent to, the additional agent. In certain embodiments, a first agent is administered locally, e.g., a therapeutic agent of any of categories (i)-(iii) can be coupled to a tumor targeting agent, e.g., a tumor-targeting antibody (e.g., to form an antibody-drug conjugate), or any other delivery agent (e.g., a formulation such as a targeted formulation) such that administration of the first agent is localized to a desired site, e.g., a tumor site (e.g., a dendritic cell-enriched site). In one embodiment, the therapeutic agent is an antigen (e.g., a vaccine, e.g., an in situ cancer vaccine), which is targeted to the tumor environment, thus resulting in activation of dendritic cells. The therapeutic agent also can be locally administered, e.g., injected, at a tumor site (e.g., intratumoral or peritumoral administration). Localized delivery or administration of the therapeutic agent can reduce one or more side effects or toxicities that would otherwise be associated with systemic administration of the therapeutic agent. In one exemplary embodiment, a therapeutic agent (e.g., STING or a TLR) can be conjugated to a tumor-binding antibody (e.g., an antibody that binds to HER2), thereby delivering the therapeutic agent to a HER-2-expressing cell.

When administered in combination, the first agent, the additional agent (e.g., second or third agent), or all, can be administered in an amount or dose that is higher, lower or the same than the amount or dosage of each agent used individually, e.g., as a monotherapy. In certain embodiments, the administered amount or dosage of the first agent, the additional agent (e.g., second or third agent), or all, is lower (e.g., at least 20%, at least 30%, at least 40%, or at least 50%) than the amount or dosage of each agent used individually, e.g., as a monotherapy.

DETAILED DESCRIPTION

Disclosed herein, at least in part, are methods and compositions comprising a combination of two, three or more therapeutic agents chosen from one, two, or all of the following categories (i)-(iii): (i) an agent that enhances antigen presentation (e.g., tumor antigen presentation) (e.g., by enhancing one or more of dendritic cell activity or maturation, antigen uptake, or antigen processing); (ii) an agent that enhances an effector cell response (e.g., an immune effector cell response, e.g., B cell and/or T cell activation and/or mobilization, e.g., in the lymph node); or (iii) an agent that decreases tumor immunosuppression (e.g., increasing T cell infiltration and tumor cell killing). In some embodiments, the combination includes a PD-1 inhibitor (e.g., an anti-PD-1 antibody molecule as described herein). Without wishing to be bound by theory, it is believed that therapeutic approaches that enhance anti-tumor immunity work more effectively when the immune response is optimized via multiple targets at different stages of the immune response. Each of these stages in depicted in schematic form in FIG. 15. For example, approaches that result in activation of dendritic cells combined with approaches that enhance cellular and humoral immune can result in a more effective and/or prolonged therapeutic response.

Additional terms are defined below and throughout the application.

As used herein, the articles “a” and “an” refer to one or to more than one (e.g., to at least one) of the grammatical object of the article.

The term “or” is used herein to mean, and is used interchangeably with, the term “and/or”, unless context clearly indicates otherwise.

“About” and “approximately” shall generally mean an acceptable degree of error for the quantity measured given the nature or precision of the measurements. Exemplary degrees of error are within 20 percent (%), typically, within 10%, and more typically, within 5% of a given value or range of values.

By “a combination” or “in combination with,” it is not intended to imply that the therapy or the therapeutic agents must be administered at the same time and/or formulated for delivery together, although these methods of delivery are within the scope described herein. The therapeutic agents in the combination can be administered concurrently with, prior to, or subsequent to, one or more other additional therapies or therapeutic agents. The therapeutic agents or therapeutic protocol can be administered in any order. In general, each agent will be administered at a dose and/or on a time schedule determined for that agent. In will further be appreciated that the additional therapeutic agent utilized in this combination may be administered together in a single composition or administered separately in different compositions. In general, it is expected that additional therapeutic agents utilized in combination be utilized at levels that do not exceed the levels at which they are utilized individually. In some embodiments, the levels utilized in combination will be lower than those utilized individually.

In embodiments, the additional therapeutic agent is administered at a therapeutic or lower-than therapeutic dose. In certain embodiments, the concentration of the second therapeutic agent that is required to achieve inhibition, e.g., growth inhibition, is lower when the second therapeutic agent is administered in combination with the first therapeutic agent, e.g., the anti-PD-1 antibody molecule, than when the second therapeutic agent is administered individually. In certain embodiments, the concentration of the first therapeutic agent that is required to achieve inhibition, e.g., growth inhibition, is lower when the first therapeutic agent is administered in combination with the second therapeutic agent than when the first therapeutic agent is administered individually. In certain embodiments, in a combination therapy, the concentration of the second therapeutic agent that is required to achieve inhibition, e.g., growth inhibition, is lower than the therapeutic dose of the second therapeutic agent as a monotherapy, e.g., 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower. In certain embodiments, in a combination therapy, the concentration of the first therapeutic agent that is required to achieve inhibition, e.g., growth inhibition, is lower than the therapeutic dose of the first therapeutic agent as a monotherapy, e.g., 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower.

The terms “tumor” and “cancer” are used interchangeably herein, e.g., both terms encompass solid and liquid, e.g., diffuse or circulating, tumors. As used herein, the term “cancer” or “tumor” includes premalignant, as well as malignant cancers and tumors.

The term “antigen presenting cell” or “APC” refers to an immune system cell such as an accessory cell (e.g., a B-cell, a dendritic cell, and the like) that displays a foreign antigen complexed with major histocompatibility complexes (MHC's) on its surface. T-cells may recognize these complexes using their T-cell receptors (TCRs). APCs process antigens and present them to T-cells.

“Immune effector cell,” or “effector cell” as that term is used herein, refers to a cell that is involved in an immune response, e.g., in the promotion of an immune effector response. Examples of immune effector cells include T cells, e.g., alpha/beta T cells and gamma/delta T cells, B cells, natural killer (NK) cells, natural killer T (NKT) cells, mast cells, and myeloid-derived phagocytes.

“Immune effector” or “effector” “function” or “response,” as that term is used herein, refers to function or response, e.g., of an immune effector cell, that enhances or promotes an immune attack of a target cell. E.g., an immune effector function or response refers a property of a T or NK cell that promotes killing or the inhibition of growth or proliferation, of a target cell. In the case of a T cell, primary stimulation and co-stimulation are examples of immune effector function or response.

The term “effector function” refers to a specialized function of a cell. Effector function of a T cell, for example, may be cytolytic activity or helper activity including the secretion of cytokines.

As used herein, the terms “treat”, “treatment” and “treating” refer to the reduction or amelioration of the progression, severity and/or duration of a disorder, e.g., a proliferative disorder, or the amelioration of one or more symptoms (preferably, one or more discernible symptoms) of the disorder resulting from the administration of one or more therapies. In specific embodiments, the terms “treat,” “treatment” and “treating” refer to the amelioration of at least one measurable physical parameter of a proliferative disorder, such as growth of a tumor, not necessarily discernible by the patient. In other embodiments the terms “treat”, “treatment” and “treating”-refer to the inhibition of the progression of a proliferative disorder, either physically by, e.g., stabilization of a discernible symptom, physiologically by, e.g., stabilization of a physical parameter, or both. In other embodiments the terms “treat”, “treatment” and “treating” refer to the reduction or stabilization of tumor size or cancerous cell count.

The compositions and methods of the present invention encompass polypeptides and nucleic acids having the sequences specified, or sequences substantially identical or similar thereto, e.g., sequences at least 70%, 75%, 80%, 85%, 90%, 95% identical or higher to the sequence specified. In the context of an amino acid sequence, the term “substantially identical” is used herein to refer to a first amino acid that contains a sufficient or minimum number of amino acid residues that are i) identical to, or ii) conservative substitutions of aligned amino acid residues in a second amino acid sequence such that the first and second amino acid sequences can have a common structural domain and/or common functional activity. For example, amino acid sequences that contain a common structural domain having at least about 85%, 90%. 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to a reference sequence, e.g., a sequence provided herein.

In the context of nucleotide sequence, the term “substantially identical” is used herein to refer to a first nucleic acid sequence that contains a sufficient or minimum number of nucleotides that are identical to aligned nucleotides in a second nucleic acid sequence such that the first and second nucleotide sequences encode a polypeptide having common functional activity, or encode a common structural polypeptide domain or a common functional polypeptide activity. For example, nucleotide sequences having at least about 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to a reference sequence, e.g., a sequence provided herein.

The term “functional variant” refers to polypeptides that have a substantially identical amino acid sequence to the naturally-occurring sequence, or are encoded by a substantially identical nucleotide sequence, and are capable of having one or more activities of the naturally-occurring sequence.

Calculations of homology or sequence identity between sequences (the terms are used interchangeably herein) are performed as follows.

To determine the percent identity of two amino acid sequences, or of two nucleic acid sequences, the sequences are aligned for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second amino acid or nucleic acid sequence for optimal alignment and non-homologous sequences can be disregarded for comparison purposes). In a preferred embodiment, the length of a reference sequence aligned for comparison purposes is at least 30%, preferably at least 40%, more preferably at least 50%, 60%, and even more preferably at least 70%, 80%, 90%, 100% of the length of the reference sequence. The amino acid residues or nucleotides at corresponding amino acid positions or nucleotide positions are then compared. When a position in the first sequence is occupied by the same amino acid residue or nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position (as used herein amino acid or nucleic acid “identity” is equivalent to amino acid or nucleic acid “homology”).

The percent identity between the two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps, and the length of each gap, which need to be introduced for optimal alignment of the two sequences.

The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm. In a preferred embodiment, the percent identity between two amino acid sequences is determined using the Needleman and Wunsch ((1970) J. Mol. Biol. 48:444-453) algorithm which has been incorporated into the GAP program in the GCG software package (available at http://www.gcg.com), using either a Blossum 62 matrix or a PAM250 matrix, and a gap weight of 16, 14, 12, 10, 8, 6, or 4 and a length weight of 1, 2, 3, 4, 5, or 6. In yet another preferred embodiment, the percent identity between two nucleotide sequences is determined using the GAP program in the GCG software package (available at http://www.gcg.com), using a NWSgapdna.CMP matrix and a gap weight of 40, 50, 60, 70, or 80 and a length weight of 1, 2, 3, 4, 5, or 6. A particularly preferred set of parameters (and the one that should be used unless otherwise specified) are a Blossum 62 scoring matrix with a gap penalty of 12, a gap extend penalty of 4, and a frameshift gap penalty of 5.

The percent identity between two amino acid or nucleotide sequences can be determined using the algorithm of E. Meyers and W. Miller ((1989) CABIOS, 4:11-17) which has been incorporated into the ALIGN program (version 2.0), using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4.

The nucleic acid and protein sequences described herein can be used as a “query sequence” to perform a search against public databases to, for example, identify other family members or related sequences. Such searches can be performed using the NBLAST and XBLAST programs (version 2.0) of Altschul, et al. (1990) J. Mol. Biol. 215:403-10. BLAST nucleotide searches can be performed with the NBLAST program, score=100, wordlength=12 to obtain nucleotide sequences homologous to a nucleic acid (SEQ ID NO: 1) molecules of the invention. BLAST protein searches can be performed with the XBLAST program, score=50, wordlength=3 to obtain amino acid sequences homologous to protein molecules of the invention. To obtain gapped alignments for comparison purposes, Gapped BLAST can be utilized as described in Altschul et al., (1997) Nucleic Acids Res. 25:3389-3402. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs (e.g., XBLAST and NBLAST) can be used. See http://www.ncbi.nlm.nih.gov.

As used herein, the term “hybridizes under low stringency, medium stringency, high stringency, or very high stringency conditions” describes conditions for hybridization and washing. Guidance for performing hybridization reactions can be found in Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6, which is incorporated by reference. Aqueous and nonaqueous methods are described in that reference and either can be used. Specific hybridization conditions referred to herein are as follows: 1) low stringency hybridization conditions in 6× sodium chloride/sodium citrate (SSC) at about 45° C., followed by two washes in 0.2×SSC, 0.1% SDS at least at 50° C. (the temperature of the washes can be increased to 55C for low stringency conditions); 2) medium stringency hybridization conditions in 6×SSC at about 45° C., followed by one or more washes in 0.2×SSC, 0.1% SDS at 60° C.; 3) high stringency hybridization conditions in 6×SSC at about 45° C., followed by one or more washes in 0.2×SSC, 0.1% SDS at 65° C.; and preferably 4) very high stringency hybridization conditions are 0.5M sodium phosphate, 7% SDS at 65° C., followed by one or more washes at 0.2×SSC, 1% SDS at 65° C. Very high stringency conditions (4) are the preferred conditions and the ones that should be used unless otherwise specified.

It is understood that the molecules of the present invention may have additional conservative or non-essential amino acid substitutions, which do not have a substantial effect on their functions.

The term “amino acid” is intended to embrace all molecules, whether natural or synthetic, which include both an amino functionality and an acid functionality and capable of being included in a polymer of naturally-occurring amino acids. Exemplary amino acids include naturally-occurring amino acids; analogs, derivatives and congeners thereof; amino acid analogs having variant side chains; and all stereoisomers of any of any of the foregoing. As used herein the term “amino acid” includes both the D- or L-optical isomers and peptidomimetics.

A “conservative amino acid substitution” is one in which the amino acid residue is replaced with an amino acid residue having a similar side chain. Families of amino acid residues having similar side chains have been defined in the art. These families include amino acids with basic side chains (e.g., lysine, arginine, histidine), acidic side chains (e.g., aspartic acid, glutamic acid), uncharged polar side chains (e.g., glycine, asparagine, glutamine, serine, threonine, tyrosine, cysteine), nonpolar side chains (e.g., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, tryptophan), beta-branched side chains (e.g., threonine, valine, isoleucine) and aromatic side chains (e.g., tyrosine, phenylalanine, tryptophan, histidine).

The terms “polypeptide”, “peptide” and “protein” (if single chain) are used interchangeably herein to refer to polymers of amino acids of any length. The polymer may be linear or branched, it may comprise modified amino acids, and it may be interrupted by non-amino acids. The terms also encompass an amino acid polymer that has been modified; for example, disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation, such as conjugation with a labeling component. The polypeptide can be isolated from natural sources, can be a produced by recombinant techniques from a eukaryotic or prokaryotic host, or can be a product of synthetic procedures.

The terms “nucleic acid,” “nucleic acid sequence,” “nucleotide sequence,” or “polynucleotide sequence,” and “polynucleotide” are used interchangeably. They refer to a polymeric form of nucleotides of any length, either deoxyribonucleotides or ribonucleotides, or analogs thereof. The polynucleotide may be either single-stranded or double-stranded, and if single-stranded may be the coding strand or non-coding (antisense) strand. A polynucleotide may comprise modified nucleotides, such as methylated nucleotides and nucleotide analogs. The sequence of nucleotides may be interrupted by non-nucleotide components. A polynucleotide may be further modified after polymerization, such as by conjugation with a labeling component. The nucleic acid may be a recombinant polynucleotide, or a polynucleotide of genomic, cDNA, semisynthetic, or synthetic origin which either does not occur in nature or is linked to another polynucleotide in a nonnatural arrangement.

The term “isolated,” as used herein, refers to material that is removed from its original or native environment (e.g., the natural environment if it is naturally occurring). For example, a naturally-occurring polynucleotide or polypeptide present in a living animal is not isolated, but the same polynucleotide or polypeptide, separated by human intervention from some or all of the co-existing materials in the natural system, is isolated. Such polynucleotides could be part of a vector and/or such polynucleotides or polypeptides could be part of a composition, and still be isolated in that such vector or composition is not part of the environment in which it is found in nature.

Various aspects of the invention are described in further detail below. Additional definitions are set out throughout the specification.

Antibody Molecules

In one embodiment, the antibody molecule binds to a mammalian, e.g., human, LAG-3. For example, the antibody molecule binds specifically to an epitope, e.g., linear or conformational epitope, (e.g., an epitope as described herein) on LAG-3. In some embodiments, the antibody molecule binds to one or more extracellular Ig-like domains of LAG-3, e.g., the first, second, third or fourth extracellular Ig-like domain of LAG-3.

As used herein, the term “antibody molecule” refers to a protein, e.g., an immunoglobin chain or fragment thereof, comprising at least one immunoglobulin variable domain sequence. The term “antibody molecule” includes, for example, a monoclonal antibody (including a full length antibody which has an immunoglobulin Fc region). In an embodiment, an antibody molecule comprises a full length antibody, or a full length immunoglobin chain. In an embodiment, an antibody molecule comprises an antigen binding or functional fragment of a full length antibody, or a full length immunoglobulin chain.

In an embodiment, an antibody molecule is a monospecific antibody molecule and binds a single epitope. E.g., a monospecific antibody molecule having a plurality of immunoglobulin variable domain sequences, each of which binds the same epitope.

In an embodiment an antibody molecule is a multispecific antibody molecule, e.g., it comprises a plurality of immunoglobulin variable domains sequences, wherein a first immunoglobulin variable domain sequence of the plurality has binding specificity for a first epitope and a second immunoglobulin variable domain sequence of the plurality has binding specificity for a second epitope. In an embodiment the first and second epitopes are on the same antigen, e.g., the same protein (or subunit of a multimeric protein). In an embodiment the first and second epitopes overlap. In an embodiment the first and second epitopes do not overlap. In an embodiment the first and second epitopes are on different antigens, e.g., the different proteins (or different subunits of a multimeric protein). In an embodiment a multispecific antibody molecule comprises a third, fourth or fifth immunoglobulin variable domain. In an embodiment, a multispecific antibody molecule is a bispecific antibody molecule, a trispecific antibody molecule, or tetraspecific antibody molecule,

In an embodiment a multispecific antibody molecule is a bispecific antibody molecule. A bispecific antibody has specificity for no more than two antigens. A bispecific antibody molecule is characterized by a first immunoglobulin variable domain sequence which has binding specificity for a first epitope and a second immunoglobulin variable domain sequence that has binding specificity for a second epitope. In an embodiment the first and second epitopes are on the same antigen, e.g., the same protein (or subunit of a multimeric protein). In an embodiment the first and second epitopes overlap. In an embodiment the first and second epitopes do not overlap. In an embodiment the first and second epitopes are on different antigens, e.g., the different proteins (or different subunits of a multimeric protein). In an embodiment a bispecific antibody molecule comprises a heavy chain variable domain sequence and a light chain variable domain sequence which have binding specificity for a first epitope and a heavy chain variable domain sequence and a light chain variable domain sequence which have binding specificity for a second epitope. In an embodiment a bispecific antibody molecule comprises a half antibody having binding specificity for a first epitope and a half antibody having binding specificity for a second epitope. In an embodiment a bispecific antibody molecule comprises a half antibody, or fragment thereof, having binding specificity for a first epitope and a half antibody, or fragment thereof, having binding specificity for a second epitope. In an embodiment a bispecific antibody molecule comprises a scFv, or fragment thereof, have binding specificity for a first epitope and a scFv, or fragment thereof, have binding specificity for a second epitope. In an embodiment, the first epitope is located on LAG-3 and the second epitope is located on a PD-1, TIM-3, CEACAM (e.g., CEACAM-1, CEACAM-3 and/or CEACAM-5), PD-L1, or PD-L2.

In an embodiment, an antibody molecule comprises a diabody, and a single-chain molecule, as well as an antigen-binding fragment of an antibody (e.g., Fab, F(ab′)₂, and Fv). For example, an antibody molecule can include a heavy (H) chain variable domain sequence (abbreviated herein as VH), and a light (L) chain variable domain sequence (abbreviated herein as VL). In an embodiment an antibody molecule comprises or consists of a heavy chain and a light chain (referred to herein as a half antibody. In another example, an antibody molecule includes two heavy (H) chain variable domain sequences and two light (L) chain variable domain sequence, thereby forming two antigen binding sites, such as Fab, Fab′, F(ab′)₂, Fc, Fd, Fd′, Fv, single chain antibodies (scFv for example), single variable domain antibodies, diabodies (Dab) (bivalent and bispecific), and chimeric (e.g., humanized) antibodies, which may be produced by the modification of whole antibodies or those synthesized de novo using recombinant DNA technologies. These functional antibody fragments retain the ability to selectively bind with their respective antigen or receptor. Antibodies and antibody fragments can be from any class of antibodies including, but not limited to, IgG, IgA, IgM, IgD, and IgE, and from any subclass (e.g., IgG1, IgG2, IgG3, and IgG4) of antibodies. The a preparation of antibody molecules can be monoclonal or polyclonal. An antibody molecule can also be a human, humanized, CDR-grafted, or in vitro generated antibody. The antibody can have a heavy chain constant region chosen from, e.g., IgG1, IgG2, IgG3, or IgG4. The antibody can also have a light chain chosen from, e.g., kappa or lambda. The term “immunoglobulin” (Ig) is used interchangeably with the term “antibody” herein.

Examples of antigen-binding fragments of an antibody molecule include: (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) a F(ab′)2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, (v) a diabody (dAb) fragment, which consists of a VH domain; (vi) a camelid or camelized variable domain; (vii) a single chain Fv (scFv), see e.g., Bird et al. (1988) Science 242:423-426; and Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85:5879-5883); (viii) a single domain antibody. These antibody fragments are obtained using conventional techniques known to those with skill in the art, and the fragments are screened for utility in the same manner as are intact antibodies.

The term “antibody” includes intact molecules as well as functional fragments thereof. Constant regions of the antibodies can be altered, e.g., mutated, to modify the properties of the antibody (e.g., to increase or decrease one or more of: Fc receptor binding, antibody glycosylation, the number of cysteine residues, effector cell function, or complement function).

Antibodies of the present invention can also be single domain antibodies. Single domain antibodies can include antibodies whose complementary determining regions are part of a single domain polypeptide. Examples include, but are not limited to, heavy chain antibodies, antibodies naturally devoid of light chains, single domain antibodies derived from conventional 4-chain antibodies, engineered antibodies and single domain scaffolds other than those derived from antibodies. Single domain antibodies may be any of the art, or any future single domain antibodies. Single domain antibodies may be derived from any species including, but not limited to mouse, human, camel, llama, fish, shark, goat, rabbit, and bovine. According to another aspect of the invention, a single domain antibody is a naturally occurring single domain antibody known as heavy chain antibody devoid of light chains. Such single domain antibodies are disclosed in WO 94/04678, for example. For clarity reasons, this variable domain derived from a heavy chain antibody naturally devoid of light chain is known herein as a VHH or nanobody to distinguish it from the conventional VH of four chain immunoglobulins. Such a VHH molecule can be derived from antibodies raised in Camelidae species, for example in camel, llama, dromedary, alpaca and guanaco. Other species besides Camelidae may produce heavy chain antibodies naturally devoid of light chain; such VHHs are within the scope of the invention.

The VH and VL regions can be subdivided into regions of hypervariability, termed “complementarity determining regions” (CDR), interspersed with regions that are more conserved, termed “framework regions” (FR or FW). The extent of the framework region and CDRs has been precisely defined by a number of methods (see, Kabat, E. A., et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242; Chothia, C. et al. (1987) J. Mol. Biol. 196:901-917; and the AbM definition used by Oxford Molecular's AbM antibody modeling software. See, generally, e.g., Protein Sequence and Structure Analysis of Antibody Variable Domains. In: Antibody Engineering Lab Manual (Ed.: Duebel, S. and Kontermann, R., Springer-Verlag, Heidelberg).

The terms “complementarity determining region,” and “CDR,” as used herein refer to the sequences of amino acids within antibody variable regions which confer antigen specificity and binding affinity. In general, there are three CDRs in each heavy chain variable region (HCDR1, HCDR2, HCDR3) and three CDRs in each light chain variable region (LCDR1, LCDR2, LCDR3).

The precise amino acid sequence boundaries of a given CDR can be determined using any of a number of well-known schemes, including those described by Kabat et al. (1991), “Sequences of Proteins of Immunological Interest,” 5th Ed. Public Health Service, National Institutes of Health, Bethesda, Md. (“Kabat” numbering scheme), Al-Lazikani et al., (1997) JMB 273,927-948 (“Chothia” numbering scheme). As used herein, the CDRs defined according the “Chothia” number scheme are also sometimes referred to as “hypervariable loops.”

For example, under Kabat, the CDR amino acid residues in the heavy chain variable domain (VH) are numbered 31-35 (HCDR1), 50-65 (HCDR2), and 95-102 (HCDR3); and the CDR amino acid residues in the light chain variable domain (VL) are numbered 24-34 (LCDR1), 50-56 (LCDR2), and 89-97 (LCDR3). Under Chothia the CDR amino acids in the VH are numbered 26-32 (HCDR1), 52-56 (HCDR2), and 95-102 (HCDR3); and the amino acid residues in VL are numbered 26-32 (LCDR1), 50-52 (LCDR2), and 91-96 (LCDR3). By combining the CDR definitions of both Kabat and Chothia, the CDRs consist of amino acid residues 26-35 (HCDR1), 50-65 (HCDR2), and 95-102 (HCDR3) in human VH and amino acid residues 24-34 (LCDR1), 50-56 (LCDR2), and 89-97 (LCDR3) in human VL.

Generally, unless specifically indicated, the anti-LAG-3 antibody molecules can include any combination of one or more Kabat CDRs and/or Chothia hypervariable loops, e.g., described in Table 1. In one embodiment, the following definitions are used for the anti-LAG-3 antibody molecules described in Table 1: HCDR1 according to the combined CDR definitions of both Kabat and Chothia, and HCCDRs 2-3 and LCCDRs 1-3 according the CDR definition of Kabat. Under all definitions, each VH and VL typically includes three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4.

As used herein, an “immunoglobulin variable domain sequence” refers to an amino acid sequence which can form the structure of an immunoglobulin variable domain. For example, the sequence may include all or part of the amino acid sequence of a naturally-occurring variable domain. For example, the sequence may or may not include one, two, or more N- or C-terminal amino acids, or may include other alterations that are compatible with formation of the protein structure.

The term “antigen-binding site” refers to the part of an antibody molecule that comprises determinants that form an interface that binds to the LAG-3 polypeptide, or an epitope thereof. With respect to proteins (or protein mimetics), the antigen-binding site typically includes one or more loops (of at least four amino acids or amino acid mimics) that form an interface that binds to the LAG-3 polypeptide. Typically, the antigen-binding site of an antibody molecule includes at least one or two CDRs and/or hypervariable loops, or more typically at least three, four, five or six CDRs and/or hypervariable loops.

The terms “compete” or “cross-compete” are used interchangeably herein to refer to the ability of an antibody molecule to interfere with binding of an anti-LAG-3 antibody molecule, e.g., an anti-LAG-3 antibody molecule provided herein, to a target, e.g., human LAG-3. The interference with binding can be direct or indirect (e.g., through an allosteric modulation of the antibody molecule or the target). The extent to which an antibody molecule is able to interfere with the binding of another antibody molecule to the target, and therefore whether it can be said to compete, can be determined using a competition binding assay, for example, a FACS assay, an ELISA or BIACORE assay. In some embodiments, a competition binding assay is a quantitative competition assay. In some embodiments, a first anti-LAG-3 antibody molecule is said to compete for binding to the target with a second anti-LAG-3 antibody molecule when the binding of the first antibody molecule to the target is reduced by 10% or more, e.g., 20% or more, 30% or more, 40% or more, 50% or more, 55% or more, 60% or more, 65% or more, 70% or more, 75% or more, 80% or more, 85% or more, 90% or more, 95% or more, 98% or more, 99% or more in a competition binding assay (e.g., a competition assay described herein).

As used herein, the term “epitope” refers to the moieties of an antigen (e.g., human LAG-3) that specifically interact with an antibody molecule. Such moieties, referred to herein as epitopic determinants, typically comprise, or are part of, elements such as amino acid side chains or sugar side chains. An epitopic determinate can be defined by methods known in the art or disclosed herein, e.g., by crystallography or by hydrogen-deuterium exchange. At least one or some of the moieties on the antibody molecule, that specifically interact with an epitopic determinant, are typically located in a CDR(s). Typically an epitope has a specific three dimensional structural characteristics. Typically an epitope has specific charge characteristics. Some epitopes are linear epitopes while others are conformational epitopes.

The terms “monoclonal antibody” or “monoclonal antibody composition” as used herein refer to a preparation of antibody molecules of single molecular composition. A monoclonal antibody composition displays a single binding specificity and affinity for a particular epitope. A monoclonal antibody can be made by hybridoma technology or by methods that do not use hybridoma technology (e.g., recombinant methods).

An “effectively human” protein is a protein that does not evoke a neutralizing antibody response, e.g., the human anti-murine antibody (HAMA) response. HAMA can be problematic in a number of circumstances, e.g., if the antibody molecule is administered repeatedly, e.g., in treatment of a chronic or recurrent disease condition. A HAMA response can make repeated antibody administration potentially ineffective because of an increased antibody clearance from the serum (see, e.g., Saleh et al., Cancer Immunol. Immunother., 32:180-190 (1990)) and also because of potential allergic reactions (see, e.g., LoBuglio et al., Hybridoma, 5:5117-5123 (1986)).

The antibody molecule can be a polyclonal or a monoclonal antibody. In other embodiments, the antibody can be recombinantly produced, e.g., produced by phage display or by combinatorial methods.

Phage display and combinatorial methods for generating antibodies are known in the art (as described in, e.g., Ladner et al. U.S. Pat. No. 5,223,409; Kang et al.

(1991) PNAS 88:7978-7982, the contents of all of which are incorporated by reference herein).

In one embodiment, the antibody is a fully human antibody (e.g., an antibody made in a mouse which has been genetically engineered to produce an antibody from a human immunoglobulin sequence), or a non-human antibody, e.g., a rodent (mouse or rat), goat, primate (e.g., monkey), camel antibody. Preferably, the non-human antibody is a rodent (mouse or rat antibody). Methods of producing rodent antibodies are known in the art.

Human monoclonal antibodies can be generated using transgenic mice carrying the human immunoglobulin genes rather than the mouse system. Splenocytes from these transgenic mice immunized with the antigen of interest are used to produce hybridomas that secrete human mAbs with specific affinities for epitopes from a human protein (see, e.g., Wood et al. International Application WO 91/00906, Kucherlapati et al. PCT publication WO 91/10741; Lonberg et al. International Application WO 92/03918; Kay et al. International Application 92/03917; Lonberg, N. et al. 1994 Nature 368:856-859; Green, L. L. et al. 1994 Nature Genet. 7:13-21; Morrison, S. L. et al. 1994 Proc. Natl. Acad. Sci. USA 81:6851-6855; Bruggeman et al. 1993 Year Immunol 7:33-40; Tuaillon et al. 1993 PNAS 90:3720-3724; Bruggeman et al. 1991 Eur J Immunol 21:1323-1326).

An antibody can be one in which the variable region, or a portion thereof, e.g., the CDRs, are generated in a non-human organism, e.g., a rat or mouse. Chimeric, CDR-grafted, and humanized antibodies are within the invention. Antibodies generated in a non-human organism, e.g., a rat or mouse, and then modified, e.g., in the variable framework or constant region, to decrease antigenicity in a human are within the invention.

Chimeric antibodies can be produced by recombinant DNA techniques known in the art (see Robinson et al., International Patent Publication PCT/US86/02269; Akira, et al., European Patent Application 184,187; Taniguchi, M., European Patent Application 171,496; Morrison et al., European Patent Application 173,494; Neuberger et al., International Application WO 86/01533; Cabilly et al. U.S. Pat. No. 4,816,567; Cabilly et al., European Patent Application 125,023; Better et al. (1988 Science 240:1041-1043); Liu et al. (1987) PNAS 84:3439-3443; Liu et al., 1987, J. Immunol. 139:3521-3526; Sun et al. (1987) PNAS 84:214-218; Nishimura et al., 1987, Canc. Res. 47:999-1005; Wood et al. (1985) Nature 314:446-449; and Shaw et al., 1988, J. Natl Cancer Inst. 80:1553-1559).

A humanized or CDR-grafted antibody will have at least one or two but generally all three recipient CDRs (of heavy and or light immuoglobulin chains) replaced with a donor CDR. The antibody may be replaced with at least a portion of a non-human CDR or only some of the CDRs may be replaced with non-human CDRs. It is only necessary to replace the number of CDRs required for binding of the humanized antibody to LAG-3. Preferably, the donor will be a rodent antibody, e.g., a rat or mouse antibody, and the recipient will be a human framework or a human consensus framework. Typically, the immunoglobulin providing the CDRs is called the “donor” and the immunoglobulin providing the framework is called the “acceptor.” In one embodiment, the donor immunoglobulin is a non-human (e.g., rodent). The acceptor framework is a naturally-occurring (e.g., a human) framework or a consensus framework, or a sequence about 85% or higher, preferably 90%, 95%, 99% or higher identical thereto.

As used herein, the term “consensus sequence” refers to the sequence formed from the most frequently occurring amino acids (or nucleotides) in a family of related sequences (See e.g., Winnaker, From Genes to Clones (Verlagsgesellschaft, Weinheim, Germany 1987). In a family of proteins, each position in the consensus sequence is occupied by the amino acid occurring most frequently at that position in the family. If two amino acids occur equally frequently, either can be included in the consensus sequence. A “consensus framework” refers to the framework region in the consensus immunoglobulin sequence.

An antibody can be humanized by methods known in the art (see e.g., Morrison, S. L., 1985, Science 229:1202-1207, by Oi et al., 1986, BioTechniques 4:214, and by Queen et al. U.S. Pat. No. 5,585,089, U.S. Pat. No. 5,693,761 and U.S. Pat. No. 5,693,762, the contents of all of which are hereby incorporated by reference).

Humanized or CDR-grafted antibodies can be produced by CDR-grafting or CDR substitution, wherein one, two, or all CDRs of an immunoglobulin chain can be replaced. See e.g., U.S. Pat. No. 5,225,539; Jones et al. 1986 Nature 321:552-525; Verhoeyan et al. 1988 Science 239:1534; Beidler et al. 1988 J. Immunol. 141:4053-4060; Winter U.S. Pat. No. 5,225,539, the contents of all of which are hereby expressly incorporated by reference. Winter describes a CDR-grafting method which may be used to prepare the humanized antibodies of the present invention (UK Patent Application GB 2188638A, filed on Mar. 26, 1987; Winter U.S. Pat. No. 5,225,539), the contents of which is expressly incorporated by reference.

Also within the scope of the invention are humanized antibodies in which specific amino acids have been substituted, deleted or added. Criteria for selecting amino acids from the donor are described in U.S. Pat. No. 5,585,089, e.g., columns 12-16 of U.S. Pat. No. 5,585,089, the e.g., columns 12-16 of U.S. Pat. No. 5,585,089, the contents of which are hereby incorporated by reference. Other techniques for humanizing antibodies are described in Padlan et al. EP 519596 A1, published on Dec. 23, 1992.

The antibody molecule can be a single chain antibody. A single-chain antibody (scFV) may be engineered (see, for example, Colcher, D. et al. (1999) Ann NY Acad Sci 880:263-80; and Reiter, Y. (1996) Clin Cancer Res 2:245-52). The single chain antibody can be dimerized or multimerized to generate multivalent antibodies having specificities for different epitopes of the same target protein.

In yet other embodiments, the antibody molecule has a heavy chain constant region chosen from, e.g., the heavy chain constant regions of IgG, IgG2, IgG3, IgG4, IgM, IgA1, IgA2, IgD, and IgE; particularly, chosen from, e.g., the (e.g., human) heavy chain constant regions of IgG1, IgG2, IgG3, and IgG4. In another embodiment, the antibody molecule has a light chain constant region chosen from, e.g., the (e.g., human) light chain constant regions of kappa or lambda. The constant region can be altered, e.g., mutated, to modify the properties of the antibody (e.g., to increase or decrease one or more of: Fc receptor binding, antibody glycosylation, the number of cysteine residues, effector cell function, and/or complement function). In one embodiment the antibody has: effector function; and can fix complement. In other embodiments the antibody does not; recruit effector cells; or fix complement. In another embodiment, the antibody has reduced or no ability to bind an Fc receptor. For example, it is an isotype or subtype, fragment or other mutant, which does not support binding to an Fc receptor, e.g., it has a mutagenized or deleted Fc receptor binding region.

Methods for altering an antibody constant region are known in the art. Antibodies with altered function, e.g., altered affinity for an effector ligand, such as FcR on a cell, or the C1 component of complement can be produced by replacing at least one amino acid residue in the constant portion of the antibody with a different residue (see e.g., EP 388,151 A1, U.S. Pat. No. 5,624,821 and U.S. Pat. No. 5,648,260, the contents of all of which are hereby incorporated by reference). Similar type of alterations could be described which if applied to the murine, or other species immunoglobulin would reduce or eliminate these functions.

An antibody molecule can be derivatized or linked to another functional molecule (e.g., another peptide or protein). As used herein, a “derivatized” antibody molecule is one that has been modified. Methods of derivatization include but are not limited to the addition of a fluorescent moiety, a radionucleotide, a toxin, an enzyme or an affinity ligand such as biotin. Accordingly, the antibody molecules of the invention are intended to include derivatized and otherwise modified forms of the antibodies described herein, including immunoadhesion molecules. For example, an antibody molecule can be functionally linked (by chemical coupling, genetic fusion, noncovalent association or otherwise) to one or more other molecular entities, such as another antibody (e.g., a bispecific antibody or a diabody), a detectable agent, a cytotoxic agent, a pharmaceutical agent, and/or a protein or peptide that can mediate association of the antibody or antibody portion with another molecule (such as a streptavidin core region or a polyhistidine tag).

One type of derivatized antibody molecule is produced by crosslinking two or more antibodies (of the same type or of different types, e.g., to create bispecific antibodies). Suitable crosslinkers include those that are heterobifunctional, having two distinctly reactive groups separated by an appropriate spacer (e.g., m-maleimidobenzoyl-N-hydroxysuccinimide ester) or homobifunctional (e.g., disuccinimidyl suberate). Such linkers are available from Pierce Chemical Company, Rockford, Ill.

Useful detectable agents with which an antibody molecule of the invention may be derivatized (or labeled) to include fluorescent compounds, various enzymes, prosthetic groups, luminescent materials, bioluminescent materials, fluorescent emitting metal atoms, e.g., europium (Eu), and other anthanides, and radioactive materials (described below). Exemplary fluorescent detectable agents include fluorescein, fluorescein isothiocyanate, rhodamine, 5dimethylamine-1-napthalenesulfonyl chloride, phycoerythrin and the like. An antibody may also be derivatized with detectable enzymes, such as alkaline phosphatase, horseradish peroxidase, β-galactosidase, acetylcholinesterase, glucose oxidase and the like. When an antibody is derivatized with a detectable enzyme, it is detected by adding additional reagents that the enzyme uses to produce a detectable reaction product. For example, when the detectable agent horseradish peroxidase is present, the addition of hydrogen peroxide and diaminobenzidine leads to a colored reaction product, which is detectable. An antibody molecule may also be derivatized with a prosthetic group (e.g., streptavidin/biotin and avidin/biotin). For example, an antibody may be derivatized with biotin, and detected through indirect measurement of avidin or streptavidin binding. Examples of suitable fluorescent materials include umbelliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylamine fluorescein, dansyl chloride or phycoerythrin; an example of a luminescent material includes luminol; and examples of bioluminescent materials include luciferase, luciferin, and aequorin.

Labeled antibody molecule can be used, for example, diagnostically and/or experimentally in a number of contexts, including (i) to isolate a predetermined antigen by standard techniques, such as affinity chromatography or immunoprecipitation; (ii) to detect a predetermined antigen (e.g., in a cellular lysate or cell supernatant) in order to evaluate the abundance and pattern of expression of the protein; (iii) to monitor protein levels in tissue as part of a clinical testing procedure, e.g., to determine the efficacy of a given treatment regimen.

An antibody molecules may be conjugated to another molecular entity, typically a label or a therapeutic (e.g., a cytotoxic or cytostatic) agent or moiety. Radioactive isotopes can be used in diagnostic or therapeutic applications. Radioactive isotopes that can be coupled to the anti-PSMA antibodies include, but are not limited to α-, β-, or γ-emitters, or β- and γ-emitters. Such radioactive isotopes include, but are not limited to iodine (¹³¹I or ¹²⁵I), yttrium (⁹⁰Y), lutetium (¹⁷⁷Lu), actinium (²²⁵Ac), praseodymium, astatine (²¹¹At), rhenium (¹⁸⁶Re), bismuth (²¹²Bi or ²¹³Bi), indium (¹¹¹In), technetium (⁹⁹mTc), phosphorus (³²P), rhodium (⁸⁸Rh), sulfur (³⁵S), carbon (¹⁴C), tritium (³H), chromium (⁵¹Cr), chlorine (³⁶Cl), cobalt (⁵⁷Co or ⁵⁸Co), iron (⁵⁹Fe), selenium (⁷⁵Se), or gallium (⁶⁷Ga). Radioisotopes useful as therapeutic agents include yttrium (⁹⁰Y), lutetium (¹⁷⁷Lu), actinium (²²⁵Ac), praseodymium, astatine (²¹¹At), rhenium (¹⁸⁶Re), bismuth (²¹²Bi or ²¹³Bi), and rhodium (⁸⁸Rh). Radioisotopes useful as labels, e.g., for use in diagnostics, include iodine (¹³¹I or ¹²⁵I), indium (¹¹¹In), technetium (⁹⁹mTc), phosphorus (³²P), carbon (¹⁴C), and tritium (³H), or one or more of the therapeutic isotopes listed above.

The invention provides radiolabeled antibody molecules and methods of labeling the same. In one embodiment, a method of labeling an antibody molecule is disclosed. The method includes contacting an antibody molecule, with a chelating agent, to thereby produce a conjugated antibody. The conjugated antibody is radiolabeled with a radioisotope, e.g., ¹¹¹Indium, ⁹⁰Yttrium and ¹⁷⁷Lutetium, to thereby produce a labeled antibody molecule.

As is discussed above, the antibody molecule can be conjugated to a therapeutic agent. Therapeutically active radioisotopes have already been mentioned. Examples of other therapeutic agents include taxol, cytochalasin B, gramicidin D, ethidium bromide, emetine, mitomycin, etoposide, tenoposide, vincristine, vinblastine, colchicine, doxorubicin, daunorubicin, dihydroxy anthracin dione, mitoxantrone, mithramycin, actinomycin D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine, lidocaine, propranolol, puromycin, maytansinoids, e.g., maytansinol (see U.S. Pat. No. 5,208,020), CC-1065 (see U.S. Pat. Nos. 5,475,092, 5,585,499, 5,846, 545) and analogs or homologs thereof. Therapeutic agents include, but are not limited to, antimetabolites (e.g., methotrexate, 6-mercaptopurine, 6-thioguanine, cytarabine, 5-fluorouracil decarbazine), alkylating agents (e.g., mechlorethamine, thioepa chlorambucil, CC-1065, melphalan, carmustine (BSNU) and lomustine (CCNU), cyclothosphamide, busulfan, dibromomannitol, streptozotocin, mitomycin C, and cis-dichlorodiamine platinum (II) (DDP) cisplatin), anthracyclinies (e.g., daunorubicin (formerly daunomycin) and doxorubicin), antibiotics (e.g., dactinomycin (formerly actinomycin), bleomycin, mithramycin, and anthramycin (AMC)), and anti-mitotic agents (e.g., vincristine, vinblastine, taxol and maytansinoids).

In one aspect, the invention features a method of providing a target binding molecule that specifically binds to a LAG-3 receptor. For example, the target binding molecule is an antibody molecule. The method includes: providing a target protein that comprises at least a portion of non-human protein, the portion being homologous to (at least 70, 75, 80, 85, 87, 90, 92, 94, 95, 96, 97, 98% identical to) a corresponding portion of a human target protein, but differing by at least one amino acid (e.g., at least one, two, three, four, five, six, seven, eight, or nine amino acids); obtaining an antibody molecule that specifically binds to the antigen; and evaluating efficacy of the binding agent in modulating activity of the target protein. The method can further include administering the binding agent (e.g., antibody molecule) or a derivative (e.g., a humanized antibody molecule) to a human subject.

This invention provides an isolated nucleic acid molecule encoding the above antibody molecule, vectors and host cells thereof. The nucleic acid molecule includes but is not limited to RNA, genomic DNA and cDNA.

TLRs are a family of pattern recognition receptors that were initially identified as sensors of the innate immune system that recognize microbial pathogens. In humans, the TLRs include TLR-1, TLR-2, TLR-3, TLR-4, TLR-5, TLR-6, TLR-7, TLR-8, TLR-9, and TLR-10. TLR-1, -2, -4, -5, and -6, are expressed on the surface of cells and TLR-3, -7/8, and -9 are expressed with the ER compartment. Human dendritic cell subsets can be identified on the basis of distinct TLR expression patterns. The myeloid or “conventional” subset of human dendritic cells express TLRs 1-8 and the plasmacytoid subset of dendritic cells express only TLR-7 and TLR-9. Ligand binding to TLRs invokes a cascade of intra-cellular signaling pathways that induce the production of factors involved in inflammation and immunity. Upon stimulation, the myeloid subset and the plasmacytoid subset of human dendritic cells result in antigen-specific CD4+ and CD8+ T cell priming and activation of NK cells and T-cells, respectively.

In some embodiments, the TLR agonist is chosen from one or more of a TLR-1 agonist, a TLR-2 agonist, a TLR-3 agonist, a TLR-4 agonist, a TLR-5 agonist, a TLR-6 agonist, a TLR-7 agonist, a TLR-8 agonist, a TLR-9 agonist, a TLR-10 agonist, a TLR-1/2 agonist, a TLR-2/6 agonist, or a TLR-7/8 agonist.

In one embodiment, a combination described herein includes a vaccine, e.g., a scaffold vaccine. In some embodiments, the combination is used to treat a cancer, e.g., a cancer described herein.

Cancer vaccines are disclosed, e.g., in PCT Publication Nos. WO 2007/070660 and WO 2012/167230, EP 1960009 B1, U.S. Pat. No. 8,067,237 and U.S. Pat. No. 8,932,583, and U.S. Publication No. US 2011/0020216. The components that can be used within cancer vaccines (e.g., implantable scaffold materials) are disclosed, e.g., in PCT Publication Nos. WO 2009/102465 and WO 2013/106852. Methods that can be used for administration of cancer vaccines are disclosed, e.g., in PCT Publication Nos. WO 2013/158673, WO 2012/048165, and WO 2012/149358.

In some embodiments, the cancer vaccine includes a macroporous scaffold comprising (i) cells or a cell recruitment composition, and (ii) a deployment signal capable of inducing or promoting migration of cells, and (iii) a bioactive composition coated or seeded onto/into the scaffold, which causes cells recruited into the scaffold be modified. Migration of the modified cells can be promoted by the open, interconnected macropores and the deployment signal.

In some embodiments, the cancer vaccine induces an endogenous immune response to a cancer target via administration of a porous scaffold bearing a recruitment composition and a target antigen composition, wherein an endogenous antigen presenting cell is recruited into the scaffold to encounter antigen and where said cell resides until a deployment signal induces egress to a lymph node tissue outside the scaffold, thereby stimulating an endogenous immune response to said cancer target.

In some embodiments, the cancer vaccine is used to remove a target cell from a mammal using a scaffold composition.

In some embodiments, an in situ cancer vaccine is generated via recruitment of cancer cells to an implanted scaffold and destruction of the cells using a cytotoxic agent.

In some embodiments, a cytosine-guanosine oligonucleotide (CpG-ODN) is used as a component of a scaffold, which can effectively reprogram and deploy dendritic cells recruited to the scaffold, and generate an effective anti-tumor response.

In some embodiments, polyinosine-polycytidylic acid (poly I:C) and/or CpG ODN are used to exert a synergistic effect on tumor inhibition.

In some embodiments, porous rods comprising an immune cell recruitment compound (e.g. GM-CSF) and an immune cell activation compound (e.g. CpG ODN), and optionally comprising an antigen such as a tumor lysate, are used, e.g., to elicit an immune response to a vaccine antigen. In some embodiments, pores that facilitate recruitment or release of cells are formed in situ within hydrogels following hydrogel injection. In some embodiments, injectable shape memory porous hydrogel polymer is used for administration.

In other embodiments, the combinations disclosed herein include a cancer or tumor vaccine. Non-limiting examples of tumor vaccines that can be used include peptides of melanoma antigens, such as peptides of gp100, MAGE antigens, Trp-2, MART1 and/or tyrosinase, tumor cells transfected to express the cytokine GM-CSF, DNA-based vaccines, RNA-based vaccines, and viral transduction-based vaccines. The cancer vaccine may be prophylactic or therapeutic.

Many experimental strategies for vaccination against tumors have been devised (see Rosenberg, S., 2000, Development of Cancer Vaccines, ASCO Educational Book Spring: 60-62; Logothetis, C., 2000, ASCO Educational Book Spring: 300-302; Khayat, D. 2000, ASCO Educational Book Spring: 414-428; Foon, K. 2000, ASCO Educational Book Spring: 730-738; see also Restifo, N. and Sznol, M., Cancer Vaccines, Ch. 61, pp. 3023-3043 in DeVita, V. et al. (eds.), 1997, Cancer: Principles and Practice of Oncology. Fifth Edition). In one of these strategies, a vaccine is prepared using autologous or allogeneic tumor cells. These cellular vaccines have been shown to be most effective when the tumor cells are transduced to express GM-CSF. GM-CSF has been shown to be a potent activator of antigen presentation for tumor vaccination (Dranoff et al. (1993) Proc. Natl. Acad. Sci. U.S.A. 90: 3539-43).

The combinations disclosed herein, e.g., LAG-3 blockade, can be used in conjunction with a collection of recombinant proteins and/or peptides expressed in a tumor in order to generate an immune response to these proteins. These proteins are normally viewed by the immune system as self antigens and are therefore tolerant to them. The tumor antigen may also include the protein telomerase, which is required for the synthesis of telomeres of chromosomes and which is expressed in more than 85% of human cancers and in only a limited number of somatic tissues (Kim, N et al. (1994) Science 266: 2011-2013). (These somatic tissues may be protected from immune attack by various means). Tumor antigen may also be “neo-antigens” expressed in cancer cells because of somatic mutations that alter protein sequence or create fusion proteins between two unrelated sequences (ie. bcr-abl in the Philadelphia chromosome), or idiotype from B cell tumors.

Other tumor vaccines may include the proteins from viruses implicated in human cancers such a Human Papilloma Viruses (HPV), Hepatitis Viruses (HBV and HCV), Kaposi's Herpes Sarcoma Virus (KHSV), and Epstein-Barr virus (EBV). Another form of tumor specific antigen which may be used in conjunction with PD-1 blockade is purified heat shock proteins (HSP) isolated from the tumor tissue itself. These heat shock proteins contain fragments of proteins from the tumor cells and these HSPs are highly efficient at delivery to antigen presenting cells for eliciting tumor immunity (Suot, R & Srivastava, P (1995) Science 269:1585-1588; Tamura, Y. et al. (1997) Science 278:117-120).

Dendritic cells (DC) are potent antigen presenting cells that can be used to prime antigen-specific responses. DC's can be produced ex vivo and loaded with various protein and peptide antigens as well as tumor cell extracts (Nestle, F. et al. (1998) Nature Medicine 4: 328-332). DCs may also be transduced by genetic means to express these tumor antigens as well. DCs have also been fused directly to tumor cells for the purposes of immunization (Kugler, A. et al. (2000) Nature Medicine 6:332-336). As a method of vaccination, DC immunization may be effectively combined with other agent, e.g., PD-1 blockade, to activate more potent anti-tumor responses.

Exemplary Bispecific T-Cell Engagers

In one embodiment, a combination described herein includes a bispecific T-cell engager. In some embodiments, the combination is used to treat a cancer, e.g., a cancer described herein, e.g., a solid tumor (e.g., a gastrointestinal cancer, a melanoma, or a lung cancer) or a hematologic malignancy (e.g., a lymphoma (e.g., non-Hodgkin's lymphoma) or a leukemia (e.g., an acute lymphoblastic leukemia).

Bi-specific T-cell engagers (BiTE®) are a class of artificial bispecific monoclonal antibodies that can direct a host's immune system, e.g., the T cells' cytotoxic activity, against cancer cells. Bi-specific T-cell engagers can form a link between T cells and tumor cells, which causes T cells to exert cytotoxic activity on tumor cells by producing proteins like perforin and granzymes, independently of the presence of MHC I or co-stimulatory molecules. These proteins enter tumor cells and initiate the cell's apoptosis. This action mimics physiological processes observed during T cell attacks against tumor cells.

In some embodiments, the bi-specific T-cell engager is a fusion protein comprising two single-chain variable fragments (scFvs) of different antibodies. In some embodiments, one of the scFvs binds to T cells, e.g., via the CD3 receptor, and the other to a tumor cell, e.g., via a tumor specific molecule.

In some embodiments, the bi-specific T-cell engager is a bispecific antibody molecule of NKG2A and CD138, or a bispecific antibody molecule of CD3 and TCR. In some embodiments, the bispecific T-cell engager is a bispecific antibody molecule that binds to CD3 and a tumor antigen (e.g., EGFR, PSCA, PSMA, EpCAM, HER2 among others).

In some embodiments, the bi-specific T-cell engager is blinatumomab (CAS Registry Number: 853426-35-4). Blinatumomab is also known as MT103. Blinatumomab specifically targets a CD3 site for T cells and a CD19 site for B cells.

In some embodiments, the bi-specific T-cell engager is MT110. MT110 is a single-chain antibody that targets EpCAM and CD3. MT110 is disclosed, e.g., in Amann et al. J Immunother. 2009; 32(5):452-64.

In some embodiments, the bi-specific T-cell engager targets melanoma-associated chondroitin sulfate proteoglycan (MCSP). In some embodiments, the bi-specific T-cell engager targets CD33. In some embodiments the bi-specific T-cell engager comprises trastuzumab (targeting HER2/neu), cetuximab, or panitumumab (both targeting the EGF receptor), a functional fragment thereof. In some embodiments, the bi-specific T-cell engager targets CD66e and EphA2.

In another embodiment, the GITR agonist is used in combination with a TLR agonist, e.g., as described in WO2004/060319, and International Publication No. WO2014/012479.

Exemplary PD-1 Inhibitors

PD-1 is a CD28/CTLA-4 family member expressed, e.g., on activated CD4⁺ and CD8⁺ T cells, T_(regs), and B cells. It negatively regulates effector T cell signaling and function. PD-1 is induced on tumor-infiltrating T cells, and can result in functional exhaustion or dysfunction (Keir et al. (2008) Annu. Rev. Immunol. 26:677-704; Pardoll et al. (2012) Nat Rev Cancer 12(4):252-64). PD-1 delivers a coinhibitory signal upon binding to either of its two ligands, Programmed Death-Ligand 1 (PD-L1) or Programmed Death-Ligand 2 (PD-L2). PD-L1 is expressed on a number of cell types, including T cells, natural killer (NK) cells, macrophages, dendritic cells (DCs), B cells, epithelial cells, vascular endothelial cells, as well as many types of tumors. High expression of PD-L1 on murine and human tumors has been linked to poor clinical outcomes in a variety of cancers (Keir et al. (2008) Annu. Rev. Immunol. 26:677-704; Pardoll et al. (2012) Nat Rev Cancer 12(4):252-64). PD-L2 is expressed on dendritic cells, macrophages, and some tumors. Blockade of the PD-1 pathway has been pre-clinically and clinically validated for cancer immunotherapy. Both preclinical and clinical studies have demonstrated that anti-PD-1 blockade can restore activity of effector T cells and results in robust anti-tumor response. For example, blockade of PD-1 pathway can restore exhausted/dysfunctional effector T cell function (e.g., proliferation, IFN-γ secretion, or cytolytic function) and/or inhibit T_(reg) cell function (Keir et al. (2008) Annu. Rev. Immunol. 26:677-704; Pardoll et al. (2012) Nat Rev Cancer 12(4):252-64). Blockade of the PD-1 pathway can be effected with an antibody, an antigen binding fragment thereof, an immunoadhesin, a fusion protein, or oligopeptide of PD-1, PD-L1 and/or PD-L2.

As used herein, the term “Programmed Death 1” or “PD-1” include isoforms, mammalian, e.g., human PD-1, species homologs of human PD-1, and analogs comprising at least one common epitope with PD-1. The amino acid sequence of PD-1, e.g., human PD-1, is known in the art, e.g., Shinohara T et al. (1994) Genomics 23(3):704-6; Finger L R, et al. Gene (1997) 197(1-2):177-87.

In one embodiment, a combination described herein includes a PD-1 inhibitor. In some embodiments, the combination is used to treat a cancer, e.g., a cancer described herein, e.g., a solid tumor or a hematologic malignancy. In some embodiments, the cancer is chosen from a thyroid cancer (e.g., an anaplastic thyroid cancer), a renal cancer (e.g., a renal cell carcinoma), a skin cancer (e.g., a melanoma), a head and neck cancer, a brain cancer (e.g., a glioblastoma), a pancreatic cancer, a nasopharyngeal cancer, a colorectal cancer, a lung cancer (e.g., a non-small cell lung cancer), a breast cancer (e.g., a triple negative breast cancer), an endometrial cancer, a liver cancer (e.g., a hepatocellular carcinoma), a bladder cancer, an ovarian cancer, an MSI-high cancer, a FoxP3-expressing cancer, or a lymphoma.

Exemplary IL-15 Agonists

In one embodiment, a combination described herein includes an interleukin-15 (IL-15) agonist. In some embodiments, the combination is used to treat a cancer, e.g., a cancer described herein, e.g., a solid tumor (e.g., a refractory solid tumor), (e.g., a melanoma (e.g., a metastatic or advanced melanoma), a kidney cancer (e.g., a renal cell cancer), a non-small cell lung cancer, a squamous cell head and neck cancer, or a bladder cancer (e.g., a non-muscle invasive bladder cancer)), e.g., a hematologic malignancy (e.g., a leukemia, e.g., an acute myelogenous leukemia (e.g., a refractory or relapsed acute myelogenous leukemia), e.g., a lymphoma, e.g., a non-Hodgkin lymphoma (e.g., a relapsed/refractory indolent B cell non-Hodgkin lymphoma), e.g., or a multiple myeloma (e.g., a relapsed or refractory multiple myeloma)).

IL-15, secreted by mononuclear phagocytes (and some other cell types) following viral infection, regulates T and natural killer cell activation and proliferation. This cytokine induces activation of transcription activators STAT3, STAT5, and STAT6 via JAK kinase signal transduction pathways in mast cells, T cells, and dendritic epidermal T cells. IL-15 and interleukin-2 (IL-2) are structurally similar and share many biological activities; both may bind to common hematopoietin receptor subunits, negatively regulating each other's activity. CD8+ memory T cell number can be regulated by a balance between IL-15 and IL-2.

In some embodiments, the IL-15 agonist is a recombinant human IL-15 (rhIL-15), e.g., CYP0150 (Cytune). CYP0150 is a recombinant protein consisting of a human IL-15 linked to the Sushi+ domain of the human alpha chain receptor (transpresentation).

Exemplary LAG-3 Inhibitors

The immune system has the capability of recognizing and eliminating tumor cells; however, tumors can use multiple strategies to evade immunity. Blockade of immune checkpoints is one of the approaches to activating or reactivating therapeutic antitumor immunity. Lymphocyte Activation Gene-3 (LAG-3) has been described as an inhibitory receptor in the immunological synapse (Chen and Flies (2013) Nat Rev Immunol. 13(4):227-42). Thus, blocking of LAG-3 can lead to enhancement of antitumor immunity.

Several cell types express LAG-3. For example, LAG-3 is expressed on activated CD4⁺ and CD8⁺ T cells, T_(reg) cells, natural killer (NK) cells, and plasmacytoid dendritic cells (DCs). LAG-3 is expressed in tumor-infiltrating lymphocytes, e.g., infiltrating lymphocytes in head and neck squamous cell carcinoma (HNSCC). LAG-3 is expressed on highly suppressive induced and natural Tregs. For example, highly suppressive FoxP3+ nTregs and FoxP3− iTregs are LAG-3 positive in melanoma and colorectal cancer (Camisaschi et al. (2010) J. Immunol. 184(11):6545-6551; Scurr et al. (2014) Mucosal. Immunol. 7(2):428-439).

LAG-3 negatively regulates T cell signaling and functions. Ligands for LAG-3 includes, e.g., MHC Class II and L-SECtin. Anti-LSECtin has been shown to inhibit B16 melanoma cell growth (Xu et al. (2014) Cancer Res. 74(13):3418-3428). Blockade of LAG-3 can restore activities of effector cells, dimish suppressor activity of T_(regs), and/or enhance anti-PD-1 antitumor activity.

LAG-3 is typically though not exclusively co-expressed on PD-1⁺ cells and single blockade can restore in vitro activities of the cells. The degree of CD8⁺ T cell exhaustion, e.g., as shown by the percentages of dual IFN-γ/TNF-α producers, correlates with the number of inhibitory receptors expressed (Blackburn et al. (2009) Nat. Immunol. 10(1): 29-37). High PD-1/LAG-3 expression correlates with T cell infiltration in melanoma. Co-blockade of LAG-3 with anti-PD-1 or PD-L1 can result in tumor suppressive activities in preclinical models. For example, anti-LAG-3 and anti-PD-1 blockade show efficacy in Sa1N fibrosarcoma and MC38 colon carcinoma models (Woo et al. (2012) Cancer Res. 72(4):917-27).

LAG-3 blockade is also efficacious in a lymphocytic choriomeningitis virus (LCMV) model. For example, PD-L1 plus LAG-3 blockade during chronic LCMV infection enhances antiviral CD8+ T cell responses (Blackburn et al. (2009) Nat. Immunol. 10(1): 29-37).

The term “Lymphocyte Activation Gene-3” or “LAG-3” include all isoforms, mammalian, e.g., human LAG-3, species homologs of human LAG-3, and analogs comprising at least one common epitope with LAG-3. The amino acid and nucleotide sequences of LAG-3, e.g., human LAG-3, is known in the art, e.g., Triebel et al. (1990) J. Exp. Med. 171:1393-1405.

In some embodiments, the combination is used to treat a cancer, e.g., a cancer described herein, e.g., a hematologic malignancy, e.g., a leukemia (e.g., chronic lymphocytic leukemia (CLL), e.g., relapsed or refractory chronic lymphocytic leukemia).

In one embodiment, the BAFF-R inhibitor is VAY736. VAY736 is a fully human combinatorial antibody library (HuCAL)-derived monoclonal antibody targeting BAFF-R. BAFF-R, also known as tumor necrosis factor receptor superfamily member 13C, is overexpressed in certain tumor cell types and autoimmune diseases. VAY736 has both anti-inflammatory and antineoplastic activities. In cancer cells, BAFF-R plays a key role in B-cell proliferation and survival. VAY736 targets and binds to BAFF-R, which inhibits both BAFF/BAFF-R interaction and BAFF-R-mediated signaling. This may decrease cell growth in tumor cells expressing BAFF-R.

VAY736 is disclosed, e.g., in U.S. Pat. No. 8,106,163. The heavy chain CDR1 of VAY736 has the amino acid sequence of GDSVSSNSAAWG (SEQ ID NO: 348) (disclosed as SEQ ID NO: 3 in U.S. Pat.

Exemplary PFKFB3 Inhibitors

In one embodiment, a combination described herein includes an inhibitor of 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3). In some embodiments, the combination is used to treat a cancer, e.g., a cancer described herein, e.g., a solid tumor (e.g., an advanced solid tumor).

In some embodiments, the PFKFB3 inhibitor is PFK-158. PFK-158 is also known as ACT-PFK-158 or (E)-1-(pyridyn-4-yl)-3-(7-(trifluoromethyl)quinolin-2-yl)-prop-2-en-1-one. PFK-158 is a derivative of 3-(3-pyridinyl)-1-[4-pyridinyl]-2-propen-1-one (3PO). PFKFB3, which catalyzes the conversion of fructose-6-phosphate to fructose-2,6-bisphosphate, is highly expressed and active in human cancer cells and plays a key role in increasing both glycolytic flux in and proliferation of cancer cells. PFKFB3 inhibitors, e.g., PFK-158, can bind to and inhibit the activity of PFKFB3, which leads to the inhibition of both the glycolytic pathway in and glucose uptake by cancer cells. This prevents the production of macromolecules and energy that causes the enhanced cellular proliferation in cancer cells as compared to that of normal, healthy cells. Depriving cancer cells of nutrients and energy leads to the inhibition of cancer cell growth.

PFK158 is disclosed, e.g., at page 5 of WO 2013/148228.

In some embodiments, the PFKFB3 inhibitor has the following structure:

Pharmaceutical Compositions and Kits

In another aspect, the present invention provides compositions, e.g., pharmaceutically acceptable compositions, which include combination molecules (e.g., antibody molecules) described herein, formulated together with a pharmaceutically acceptable carrier. As used herein, “pharmaceutically acceptable carrier” includes any and all solvents, dispersion media, isotonic and absorption delaying agents, and the like that are physiologically compatible. The carrier can be suitable for intravenous, intramuscular, subcutaneous, parenteral, rectal, spinal or epidermal administration (e.g., by injection or infusion).

The compositions of this invention may be in a variety of forms. These include, for example, liquid, semi-solid and solid dosage forms, such as liquid solutions (e.g., injectable and infusible solutions), dispersions or suspensions, liposomes and suppositories. The preferred form depends on the intended mode of administration and therapeutic application. Typical preferred compositions are in the form of injectable or infusible solutions. The preferred mode of administration is parenteral (e.g., intravenous, subcutaneous, intraperitoneal, intramuscular). In a preferred embodiment, the antibody is administered by intravenous infusion or injection. In another preferred embodiment, the antibody is administered by intramuscular or subcutaneous injection.

The phrases “parenteral administration” and “administered parenterally” as used herein means modes of administration other than enteral and topical administration, usually by injection, and includes, without limitation, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal, epidural and intrasternal injection and infusion.

Therapeutic compositions typically should be sterile and stable under the conditions of manufacture and storage. The composition can be formulated as a solution, microemulsion, dispersion, liposome, or other ordered structure suitable to high antibody concentration. Sterile injectable solutions can be prepared by incorporating the active compound (i.e., antibody or antibody portion) in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze-drying that yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof. The proper fluidity of a solution can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prolonged absorption of injectable compositions can be brought about by including in the composition an agent that delays absorption, for example, monostearate salts and gelatin.

The combination molecules (e.g., antibody molecules) can be administered by a variety of methods known in the art, although for many therapeutic applications, the preferred route/mode of administration is intravenous injection or infusion. In one embodiment, the antibody molecule is administered by intravenous infusion at a rate of more than 20 mg/min, e.g., 20-40 mg/min, and preferably greater than or equal to 40 mg/min to reach a dose of about 35 to 440 mg/m², preferably about 70 to 310 mg/m², and more preferably, about 110 to 130 mg/m². In another embodiment, the antibody molecule is administered by intravenous infusion at a rate of less than 10 mg/min; preferably less than or equal to 5 mg/min to reach a dose of about 1 to 100 mg/m², preferably about 5 to 50 mg/m², about 7 to 25 mg/m² and more preferably, about 10 mg/m². As will be appreciated by the skilled artisan, the route and/or mode of administration will vary depending upon the desired results. In certain embodiments, the active compound may be prepared with a carrier that will protect the compound against rapid release, such as a controlled release formulation, including implants, transdermal patches, and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Many methods for the preparation of such formulations are patented or generally known to those skilled in the art. See, e.g., Sustained and Controlled Release Drug Delivery Systems, J. R. Robinson, ed., Marcel Dekker, Inc., New York, 1978.

In certain embodiments, an antibody molecule can be orally administered, for example, with an inert diluent or an assimilable edible carrier. The compound (and other ingredients, if desired) may also be enclosed in a hard or soft shell gelatin capsule, compressed into tablets, or incorporated directly into the subject's diet. For oral therapeutic administration, the compounds may be incorporated with excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. To administer a compound of the invention by other than parenteral administration, it may be necessary to coat the compound with, or co-administer the compound with, a material to prevent its inactivation. Therapeutic compositions can also be administered with medical devices known in the art.

Dosage regimens are adjusted to provide the optimum desired response (e.g., a therapeutic response). For example, a single bolus may be administered, several divided doses may be administered over time or the dose may be proportionally reduced or increased as indicated by the exigencies of the therapeutic situation. It is especially advantageous to formulate parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subjects to be treated; each unit contains a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on (a) the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and (b) the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in individuals.

An exemplary, non-limiting range for a therapeutically or prophylactically effective amount of an antibody molecule is 0.1-30 mg/kg, more preferably 1-25 mg/kg. Dosages and therapeutic regimens of the anti-LAG-3 antibody molecule can be determined by a skilled artisan. In certain embodiments, the anti-LAG-3 antibody molecule is administered by injection (e.g., subcutaneously or intravenously) at a dose of about 1 to 40 mg/kg, e.g., 1 to 30 mg/kg, e.g., about 5 to 25 mg/kg, about 10 to 20 mg/kg, about 1 to 5 mg/kg, 1 to 10 mg/kg, 5 to 15 mg/kg, 10 to 20 mg/kg, 15 to 25 mg/kg, or about 3 mg/kg. The dosing schedule can vary from e.g., once a week to once every 2, 3, or 4 weeks. In one embodiment, the anti-LAG-3 antibody molecule is administered at a dose from about 10 to 20 mg/kg every other week. The antibody molecule can be administered by intravenous infusion at a rate of more than 20 mg/min, e.g., 20-40 mg/min, and preferably greater than or equal to 40 mg/min to reach a dose of about 35 to 440 mg/m², preferably about 70 to 310 mg/m², and more preferably, about 110 to 130 mg/m². In embodiments, the infusion rate of about 110 to 130 mg/m² achieves a level of about 3 mg/kg. In one embodiment, the anti-LAG-3 antibody molecule is administered (e.g., intravenously) at a dose from about 3 to 800 mg, e.g., about 3, 20, 80, 240, or 800 mg. In certain embodiments, the anti-LAG-3 antibody molecule is administered alone at a dose from about 20 to 800 mg, e.g., about 3, 20, 80, 240, or 800 mg. In other embodiments, the anti-LAG-3 antibody molecule is administered at a dose from about 3 to 240 mg, e.g., about 3, 20, 80, or 240 mg, in combination with a second agent or therapeutic modality, e.g., a second agent or therapeutic modality described herein. In one embodiment, the anti-LAG-3 antibody molecule is administered every 2 weeks (e.g., during weeks 1, 3, 5, 7) during each 8 week cycle, e.g., up to 96 weeks.

The antibody molecule can be administered by intravenous infusion at a rate of more than 20 mg/min, e.g., 20-40 mg/min, and preferably greater than or equal to 40 mg/min to reach a dose of about 35 to 440 mg/m², preferably about 70 to 310 mg/m², and more preferably, about 110 to 130 mg/m². In embodiments, the infusion rate of about 110 to 130 mg/m² achieves a level of about 3 mg/kg. In other embodiments, the antibody molecule is administered by intravenous infusion at a rate of less than 10 mg/min, e.g., less than or equal to 5 mg/min to reach a dose of about 1 to 100 mg/m², e.g., about 5 to 50 mg/m², about 7 to 25 mg/m², and more preferably, about 10 mg/m². In some embodiments, the antibody is infused over a period of about 30 min.

It is to be noted that dosage values may vary with the type and severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that dosage ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed composition.

The pharmaceutical compositions of the invention may include a “therapeutically effective amount” or a “prophylactically effective amount” of an antibody or antibody portion of the invention. A “therapeutically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired therapeutic result. A therapeutically effective amount of the modified antibody or antibody fragment may vary according to factors such as the disease state, age, sex, and weight of the individual, and the ability of the antibody or antibody portion to elicit a desired response in the individual. A therapeutically effective amount is also one in which any toxic or detrimental effects of the modified antibody or antibody fragment is outweighed by the therapeutically beneficial effects. A “therapeutically effective dosage” preferably inhibits a measurable parameter, e.g., tumor growth rate by at least about 20%, more preferably by at least about 40%, even more preferably by at least about 60%, and still more preferably by at least about 80% relative to untreated subjects. The ability of a compound to inhibit a measurable parameter, e.g., cancer, can be evaluated in an animal model system predictive of efficacy in human tumors. Alternatively, this property of a composition can be evaluated by examining the ability of the compound to inhibit, such inhibition in vitro by assays known to the skilled practitioner

A “prophylactically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired prophylactic result. Typically, since a prophylactic dose is used in subjects prior to or at an earlier stage of disease, the prophylactically effective amount will be less than the therapeutically effective amount.

Also within the scope of the invention is a kit comprising an antibody molecule described herein. The kit can include one or more other elements including: instructions for use; other reagents, e.g., a label, a therapeutic agent, or an agent useful for chelating, or otherwise coupling, an antibody to a label or therapeutic agent, or a radioprotective composition; devices or other materials for preparing the antibody for administration; pharmaceutically acceptable carriers; and devices or other materials for administration to a subject.

Uses of Anti-LAG-3 Antibody Molecules

The combinations, e.g., the anti-LAG-3 antibody molecules disclosed herein, have in vitro and in vivo diagnostic, as well as therapeutic and prophylactic utilities. For example, these molecules can be administered to cells in culture, in vitro or ex vivo, or to a subject, e.g., a human subject, e.g., in vivo, to enhance immunity. In one embodiment, the anti-LAG-3 antibody molecules enhance an immune response in a subject, e.g., by blockade of LAG-3 (e.g., by blockade of LAG-3 binding to an MHC molecule or other ligands).

Accordingly, in one aspect, the invention provides a method of modifying an immune response in a subject comprising administering to the subject the antibody, molecule described herein, such that the immune response in the subject is modified. In one embodiment, the immune response is enhanced, stimulated or up-regulated. In some embodiments, the anti-LAG-3 antibody molecule restores, enhances or stimulates an antigen-specific T cell response, e.g., interleukin-2 (IL-2) or interferon-gamma (IFN-γ), production in an antigen-specific T cell response, in the subject. In some embodiments, the immune response is an anti-tumor response. The methods and compositions described herein are suitable for treating human patients having a disorder that can be treated by augmenting the T-cell mediated immune response. For example, the anti-LAG-3 antibody molecules, alone or in combination, can be administered to a subject to treat, prevent, and/or diagnose a variety of disorders, such as cancers (melanoma or hepatic cancers), or an infectious disorder.

As used herein, the term “subject” is intended to include human and non-human animals. In one embodiment, the subject is a human subject, e.g., a human patient having a disorder or condition characterized by abnormal LAG-3 functioning. The term “non-human animals” of the invention includes mammals and non-mammals, such as non-human primates. In one embodiment, the subject is a human. In one embodiment, the subject is a human patient in need of enhancement of an immune response. In one embodiment, the subject has, or is at risk of, having a disorder described herein, e.g., a cancer or an infectious disorder as described herein. In certain embodiments, the subject is, or is at risk of being, immunocompromised. For example, the subject is undergoing or has undergone a chemotherapeutic treatment and/or radiation therapy. Alternatively, or in combination, the subject is, or is at risk of being, immunocompromised as a result of an infection. For example, the methods and compositions described herein can enhance a number of immune activities. In one embodiment, the subject has increased number or activity of tumour-infiltrating T lymphocytes (TILs). In another embodiment, the subject has increased expression or activity of interferon-gamma (IFN-γ). In yet another embodiment, the subject has decreased PD-L1 expression or activity. Accordingly, in certain embodiments, any (e.g., one, two, three, or all) of TILs, IFN-γ, CD8, or PD-L1, can be used as biomarkers for the anti-LAG-3 immunotherapies described herein.

Therapeutic Uses

Blockade of LAG-3 by antibodies can enhance an immune response to cancerous cells in a subject. Similar to CD4, LAG-3 interacts with MHC class II molecules but, unlike CD4, LAG-3 does not interact with the human immunodeficiency virus gp120 protein (Baixeras et al. (1992) J. Exp. Med. 176:327-337). Studies have demonstrated direct and specific binding of LAG-3 to MHC class II on the cell surface (Huard et al. (1996) Eur. J. Immunol. 26:1180-1186). The LAG-3/MHC class II interaction plays a role in down-regulating antigen-dependent stimulation of CD4⁺ and CD8⁺ T lymphocytes. The addition of anti-LAG-3 antibodies can result in increased T cell proliferation, higher expression of activation antigens such as CD25, and higher concentrations of cytokines such as interferon-gamma and interleukin-4 (Huard et al. (1994) Eur. J. Immunol. 24:3216-3221). The intra-cytoplasmic region of LAG-3 can also interact with LAP, a signal transduction molecule involved in the downregulation of the CD3/TCR activation pathway (Iouzalen et al. (2001) Eur. J. Immunol. 31:2885-2891). Further, LAG-3 contributes to the suppressor activity of CD4⁺CD25⁺ regulatory T cells (T_(reg)). T_(reg) cells express LAG-3 upon activation and antibodies to LAG-3 inhibit suppression by induced T_(reg) cells (Huang, C. et al. (2004) Immunity 21:503-513). LAG-3 can also negatively regulate T cell homeostasis by regulatory T cells in both T cell-dependent and independent mechanisms (Workman, C. J. and Vignali, D. A. (2005) J. Immunol. 174:688-695). Thus, inhibition of LAG-3 can result in augmenting an immune response.

Accordingly, in one aspect, a method of treating (e.g., reducing or inhibiting) a cancer or tumor in a subject is provided. The method comprises administering to the subject an anti-LAG-3 antibody molecule described herein, e.g., a therapeutically effective amount of an anti-LAG-3 antibody molecule, alone or in combination, e.g., with one or more agents or procedures. In one embodiment, an anti-LAG-3 antibody molecule may be used alone to inhibit the growth of cancerous tumors. Alternatively, an anti-LAG-3 antibody may be used in combination with one or more of: a standard of care treatment (e.g., for cancers or infectious disorders), another antibody, an immunomodulator (e.g., an activator of a costimulatory molecule or an inhibitor of an inhibitory molecule); a vaccine, e.g., a therapeutic cancer vaccine; or other forms of cellular immunotherapy, as described below. In certain embodiments, the anti-LAG-3 antibody molecule is administered in combination with a modulator of a costimulatory molecule (e.g., an agonist of a costimulatory molecule) or a modulator of an inhibitory molecule (e.g., an inhibitor of an immune checkpoint inhibitor), e.g., as described herein.

In one embodiment, the methods are suitable for the treatment of cancer in vivo. To achieve antigen-specific enhancement of immunity, the anti-LAG-3 antibody molecule can be administered together with an antigen of interest. When antibodies to LAG-3 are administered in combination with one or more agents, the combination can be administered in either order or simultaneously.

In certain embodiments, a method of treating a subject, e.g., reducing or ameliorating, a hyperproliferative condition or disorder (e.g., a cancer), e.g., solid tumor, a hematological cancer, soft tissue tumor, or a metastatic lesion, in a subject is provided. The method includes administering to the subject one or more of the combinations described herein.

As used herein, the term “cancer” is meant to include all types of cancerous growths or oncogenic processes, metastatic tissues or malignantly transformed cells, tissues, or organs, irrespective of histopathologic type or stage of invasiveness. Examples of cancerous disorders include, but are not limited to, solid tumors, hematological cancers, soft tissue tumors, and metastatic lesions. Examples of solid tumors include malignancies, e.g., sarcomas, and carcinomas (including adenocarcinomas and squamous cell carcinomas), of the various organ systems, such as those affecting liver, lung, breast, lymphoid, gastrointestinal (e.g., colon), genitourinary tract (e.g., renal, urothelial cells), prostate and pharynx. Adenocarcinomas include malignancies such as most colon cancers, rectal cancer, renal-cell carcinoma, liver cancer, non-small cell carcinoma of the lung, cancer of the small intestine and cancer of the esophagus. Squamous cell carcinomas include malignancies such as those affecting the lung, esophagus, skin, head and neck region, oral cavity, anus, and cervix. Metastatic lesions of the aforementioned cancers can also be treated or prevented using the methods and compositions of the invention.

Exemplary cancers whose growth can be inhibited using the combinations disclosed herein include cancers typically responsive to immunotherapy. Non-limiting examples of preferred cancers for treatment include melanoma (e.g., an advanced stage (e.g., stage II-IV) melanoma or an HLA-A2 positive melanoma), pancreatic cancer (e.g., advanced pancreatic cancer), solid tumors, breast cancer (e.g., metastatic breast carcinoma, a breast cancer that does not express one, two or all of estrogen receptor, progesterone receptor, or Her2/neu, e.g., a triple negative breast cancer), and renal cell carcinoma (e.g., advanced (e.g., stage IV) or metastatic renal cell carcinoma (MRCC)). Additionally, refractory or recurrent malignancies can be treated using the antibody molecules described herein.

Examples of other cancers that can be treated include, e.g., a solid tumor, e.g., prostate cancer (e.g., hormone refractory prostate adenocarcinoma), colon cancer, lung cancer (e.g., non-small cell lung cancer), bone cancer, skin cancer, cancer of the head or neck (e.g., HPV+ squamous cell carcinoma), cutaneous or intraocular malignant melanoma, uterine cancer, ovarian cancer, rectal cancer, cancer of the anal region, stomach cancer, testicular cancer, uterine cancer, carcinoma of the fallopian tubes, carcinoma of the endometrium, carcinoma of the cervix, carcinoma of the vagina, carcinoma of the vulva, Merkel cell cancer, solid tumors of childhood, cancer of the bladder, cancer of the kidney or ureter, carcinoma of the renal pelvis, neoplasm of the central nervous system (CNS), tumor angiogenesis, spinal axis tumor, brain stem glioma, pituitary adenoma, Kaposi's sarcoma, epidermoid cancer, or squamous cell cancer or a hematological malignancy, e.g., Hodgkin lymphoma, non-Hodgkin lymphoma, cancer of the esophagus, cancer of the small intestine, cancer of the endocrine system, cancer of the thyroid gland, cancer of the parathyroid gland, cancer of the adrenal gland, sarcoma of soft tissue, cancer of the urethra, cancer of the penis, chronic or acute leukemias including acute myeloid leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, chronic lymphocytic leukemia (e.g., relapsed or refractory chronic lymphocytic leukemia), solid tumors of childhood, lymphocytic lymphoma, multiple myeloma, myelodisplastic syndromes, cancer of the bladder, cancer of the kidney or ureter, carcinoma of the renal pelvis, neoplasm of the central nervous system (CNS), primary CNS lymphoma, tumor angiogenesis, spinal axis tumor, brain stem glioma, pituitary adenoma, Kaposi's sarcoma, epidermoid cancer, squamous cell cancer, T-cell lymphoma, environmentally induced cancers including those induced by asbestos (e.g., mesothelioma), and combinations of said cancers. Treatment of metastatic cancers, e.g., metastatic cancers that express MHC class II molecules or LAG-3, can be effected using the antibody molecules described herein.

While not wishing to be bound by theory, in some embodiments, a patient is more likely to respond to treatment with anti-LAG-3, alone or in combination with anti-PD-1 or PD-L1 antibody molecules (optionally in combination with one or more agents as described herein) if the patient has a cancer that highly expresses PD-L1, and/or the cancer is infiltrated by anti-tumor immune cells, e.g., TILs. The anti-tumor immune cells may be positive for CD8, PD-L1, and/or IFN-γ; thus levels of CD8, PD-L1, and/or IFN-γ can serve as a readout for levels of TILs in the microenvironment. In certain embodiments, the cancer microenvironment is referred to as triple-positive for PD-L1/CD8/IFN-γ.

Accordingly, in certain aspects, this application provides methods of determining whether a tumor sample is positive for one or more of PD-L1, CD8, and IFN-γ, and if the tumor sample is positive for one or more, e.g., two, or all three, of the markers, then administering to the patient a therapeutically effective amount of an anti-PD-1 antibody molecule, optionally in combination with one or more other immunomodulators or anti-cancer agents.

In the following indications, a large fraction of patients are triple-positive for PD-L1/CD8/IFN-γ: lung cancer (squamous); lung cancer (adenocarcinoma); head and neck cancer; stomach cancer; NSCLC; HNSCC; gastric cancers (e.g., MSIhi and/or EBV+); CRC (e.g., MSIhi); nasopharyngeal cancer (NPC); cervical cancer (e.g., squamous); thyroid cancer e.g., papillary thyroid; melanoma; TN breast cancer; and DLBCL (Diffuse Large B-Cell Lymphoma). In breast cancer generally and in colon cancer generally, a moderate fraction of patients is triple-positive for PD-L1/CD8/IFN-γ. In the following indications, a small fraction of patients are triple-positive for PD-L1/CD8/IFN-γ: ER+ breast cancer, and pancreatic cancer. These findings are discussed further in Example 4. Regardless of whether a large or small fraction of patients is triple-positive for these markers, screening the patients for these markers allows one to identify a fraction of patients that has an especially high likelihood of responding favorably to therapy with a LAG-3 antibody, alone or in combination with a PD-1 antibody (e.g., a blocking PD-1 antibody), optionally in combination with one or more other immunomodulators (e.g., an anti-TIM-3 antibody molecule or an anti-PD-L1 antibody molecule) and/or anti-cancer agents, e.g., those listed in Table 7 and disclosed in the publications listed in Table 7.

In some embodiments, the cancer sample is classified as triple-positive for PDL1/CD8/IFN-γ. This measurement can roughly be broken down into two thresholds: whether an individual cell is classified as positive, and whether the sample as a whole is classified as positive. First, one can measure, within an individual cell, the level of PD-L1, CD8, and/or IFN-γ. In some embodiments, a cell that is positive for one or more of these markers is a cell that has a higher level of the marker compared to a control cell or a reference value. For example, in some embodiments, a high level of PD-L1 in a given cell is a level higher than the level of PD-L1 in a corresponding non-cancerous tissue in the patient. As another example, in some embodiments, a high level of CD8 or IFN-γ in a given cell is a level of that protein typically seen in a TIL. Second, one can also measure the percentage of cells in the sample that are positive for PD-L1, CD8, and/or IFN-γ. (It is not necessary for a single cell to express all three markers.) In some embodiments, a triple positive sample is one that has a high percentage of cells, e.g., higher than a reference value or higher than a control sample, that are positive for these markers.

In other embodiments, one can measure the levels of PD-L1, CD8, and/or IFN-γ overall in the sample. In this case, a high level of CD8 or IFN-γ in the sample can be the level of that protein typically seen in a tumor infiltrated with TIL. Similarly, a high level of PD-L1 can be the level of that protein typically seen in a tumor sample, e.g., a tumor microenvironment.

The identification of subsets of patients that are triple-positive for PD-L1/CD8/IFN-γ, as shown in Example 4 herein, reveals certain sub-populations of patients that are likely to be especially responsive to PD-1 antibody therapy. For instance, many IM-TN (immunomodulatory, triple negative) breast cancer patients are triple-positive for PDL1/CD8/IFN-γ. IM-TN breast cancer is described in, e.g., Brian D. Lehmann et al., “Identification of human triple-negative breast cancer subtypes and preclinical models for selection of targeted therapies”, J Clin Invest. Jul. 1, 2011; 121(7): 2750-2767. Triple-negative breast cancers are those that do not express estrogen receptor (ER), progesterone receptor (PR) and Her2/neu. These cancers are difficult to treat because they are typically not responsive to agents that target ER, PR, and Her2/neu. Triple-negative breast cancers can be further subdivided into different classes, one of which is immunomodulatory. As described in Lehmann et al., IM-TN breast cancer is enriched for factors involved in immune cell processes, for example, one or more of immune cell signaling (e.g., TH1/TH2 pathway, NK cell pathway, B cell receptor signaling pathway, DC pathway, and T cell receptor signaling), cytokine signaling (e.g., cytokine pathway, IL-12 pathway, and IL-7 pathway), antigen processing and presentation, signaling through core immune signal transduction pathways (e.g., NFKB, TNF, and JAK/STAT signaling), genes involved in T-cell function, immune transcription, interferon (IFN) response and antigen processing. Accordingly, in some embodiments, the cancer treated is a cancer that is, or is determined to be, positive for one or more marker of IM-TN breast cancer, e.g., a factor that promotes one or more of immune cell signaling (e.g., TH1/TH2 pathway, NK cell pathway, B cell receptor signaling pathway, DC pathway, and T cell receptor signaling), cytokine signaling (e.g., cytokine pathway, IL-12 pathway, and IL-7 pathway), antigen processing and presentation, signaling through core immune signal transduction pathways (e.g., NFKB, TNF, and JAK/STAT signaling), genes involved in T-cell function, immune transcription, interferon (IFN) response and antigen processing.

As another example, it is shown herein that a subset of colon cancer patients having high MSI (microsatellite instability) is also triple-positive for PD-L1/CD8/IFN-γ. Accordingly, in some embodiments, a LAG-3 antibody, e.g., a LAG-3 antibody as described herein, alone or in combination with a PD-1 antibody, (optionally in combination with one or more immunomodulators such as a TIM-3 antibody or a PD-L1 antibody, and one or more anti-cancer agents, e.g., an anti-cancer agent described in Table 7 or in a publication in Table 7) is administered to a patient who has, or who is identified as having, colon cancer with high MSI, thereby treating the cancer. In some embodiments, a cell with high MSI is a cell having MSI at a level higher than a reference value or a control cell, e.g., a non-cancerous cell of the same tissue type as the cancer.

As another example, it is shown herein that a subset of gastric cancer patients having high MSI, and/or which is EBV+, is also triple-positive for PD-L1/CD8/IFN-γ. Accordingly, in some embodiments, a LAG-3 antibody, e.g., a LAG-3 antibody as described herein, alone or in combination with a PD-1 antibody, (optionally in combination with one or more immunomodulators such as a TIM-3 antibody or a PD-L1 antibody, and one or more anti-cancer agents, e.g., an anti-cancer agent described in Table 7 or in a publication in Table 7) is administered to a patient who has, or who is identified as having, gastric cancer with high MSI and/or EBV+, thereby treating the cancer. In some embodiments, a cell with high MSI is a cell having MSI at a level higher than a reference value or a control cell, e.g., a non-cancerous cell of the same tissue type as the cancer.

Additionally disclosed herein are methods of assaying a cancer for PD-L1, and then treating the cancer with a LAG-3 antibody, alone or in combination with a PD-1 antibody. As described in Example 5 herein, a cancer sample can be assayed for PD-L1 protein levels or mRNA levels. A sample having levels of PD-L1 (protein or mRNA) higher than a reference value or a control cell (e.g., a non-cancerous cell) can be classified as PD-L1 positive. Accordingly, in some embodiments, a LAG-3 antibody, e.g., a LAG-3 antibody as described herein, alone or in combination with a PD-1 antibody, (optionally in combination with one or more anti-cancer agents) is administered to a patient who has, or who is identified as having, a cancer that is PD-L1 positive. The cancer may be, e.g., non-small cell lung (NSCLC) adenocarcinoma (ACA), NSCLC squamous cell carcinoma (SCC), or hepatocellular carcinoma (HCC).

In some embodiments, the methods herein involve using a LAG-3 antibody, e.g., a LAG-3 antibody as described herein, e.g., in combination with a PD-1 antibody, for treating a cancer that is (or is identified as being) positive for PD-L1. In some embodiments, the cancer is colorectal cancer (e.g., MSI-high), gastric cancer (e.g., MSI-high and/or EBV+), NPC, cervical cancer, breast cancer (e.g., TN breast cancer), and ovarian cancer. In some embodiments, the cancer is NSCLC, melanoma, or HNSCC. In some embodiments, the LAG-3 antibody is administered at a dose of, e.g., 1, 3, 10, or 20 mg/kg.

Based on, e.g, Example 4 herein, it was found that certain gastric cancers that are triple-positive for PDL1/CD8/IFN-γ are also positive for PIK3CA. Accordingly, in some embodiments, a cancer can be treated with a LAG-3 antibody, alone or in combination with an anti-PD1 antibody molecule (optionally in combination with one or more immunomodulators, e.g., an anti-TIM-3 antibody molecule or an anti-PD-L1 antibody molecule) and an agent that inhibits PIK3CA. Exemplary agents in this category are described in Stein R C (September 2001). “Prospects for phosphoinositide 3-kinase inhibition as a cancer treatment”. Endocrine-related Cancer 8 (3): 237-48 and Marone R, Cmiljanovic V, Giese B, Wymann M P (January 2008). “Targeting phosphoinositide 3-kinase: moving towards therapy”. Biochimica et Biophysica Acta 1784 (1): 159-85.

Based on, e.g, Example 4 herein, CRC, e.g., a patient that has (or is identified as having) MSI-high CRC may be treated with a LAG-3 antibody, alone or in combination with a PD-1 antibody, optionally in combination with a therapeutic that targets one or both of RNF43 and BRAF. For instance, these cancers may be treated with a LAG-3 antibody and a PD-1 antibody, optionally in combination with one or more therapeutics that target one or more of RNF43 and BRAF. In embodiments, the one or more therapeutics include an anti-cancer agent described in Table 7 or a publication listed in Table 7. PD-1 inhibitors, e.g., antibodies, are described herein. RNF43 can be inhibited, e.g., with an antibody, small molecule (e.g., 2-(2′,3-dimethyl-[2,4′-bipyridin]-5-yl)-N-(5-(pyrazin-2-yl)pyridin-2-yl)acetamide (Compound A28)), siRNA, or a Rspo ligand or derivative thereof. BRAF inhibitors (e.g., vemurafenib or dabrafenib) are described herein.

Based on, e.g, Example 4 herein, a patient that has (or is identified as having) a squamous cell lung cancer may be treated with a LAG-3 antibody molecule in combination with a therapeutic that targets PD-1, e.g., a PD-1 antibody molecule, and optionally with one or more anti-cancer agents, e.g., an anti-cancer agent described in Table 7 or in a publication in Table 7, or a therapeutic that targets TIM-3, e.g., a TIM-3 antibody.

Based on, e.g, Example 4 herein, a patient that has (or is identified as having) a thyroid cancer may be treated with a LAG-3 antibody molecule, alone or in combination with a PD-1 antibody molecule, optionally in combination with a therapeutic that targets BRAF, and optionally in combination with one or more immunomodulators, e.g., an anti-TIM-3 antibody molecule, and an anti-PD-L1 antibody molecule. BRAF inhibitors (e.g., vemurafenib or dabrafenib) are described herein, e.g., in Table 7 and the publications listed in Table 7.

In some embodiments, the therapies here can be used to treat a patient that has (or is identified as having) a cancer associated with an infection, e.g., a viral or bacterial infection. Exemplary cancers include cervical cancer, anal cancer, HPV-associated head and neck squamous cell cancer, HPV-associated esophageal papillomas, HHV6-associated lymphomas, EBV-associated lymphomas (including Burkitt lymphoma), Gastric MALT lymphoma, other infection-associated MALT lymphomas, HCC, Kaposi's sarcoma. In other embodiments, the cancer is a hematological cancer including but is not limited to a leukemia or a lymphoma. For example, the anti-LAG-3 antibody molecule can be used to treat cancers and malignancies including, but not limited to, e.g., acute leukemias including but not limited to, e.g., B-cell acute lymphoid leukemia (“BALL”), T-cell acute lymphoid leukemia (“TALL”), acute lymphoid leukemia (ALL); one or more chronic leukemias including but not limited to, e.g., chronic myelogenous leukemia (CML), chronic lymphocytic leukemia (CLL); additional hematologic cancers or hematologic conditions including, but not limited to, e.g., B cell prolymphocytic leukemia, blastic plasmacytoid dendritic cell neoplasm, Burkitt's lymphoma, diffuse large B cell lymphoma, Follicular lymphoma, Hairy cell leukemia, small cell- or a large cell-follicular lymphoma, malignant lymphoproliferative conditions, MALT lymphoma, mantle cell lymphoma, Marginal zone lymphoma, multiple myeloma, myelodysplasia and myelodysplastic syndrome, non-Hodgkin's lymphoma, plasmablastic lymphoma, plasmacytoid dendritic cell neoplasm, Waldenstrom macroglobulinemia, and “preleukemia” which are a diverse collection of hematological conditions united by ineffective production (or dysplasia) of myeloid blood cells, and the like.

In one embodiment, the cancer is a melanoma, e.g., an advanced melanoma. In one embodiment, the cancer is an advanced or unresectable melanoma that does not respond to other therapies. In other embodiments, the cancer is a melanoma with a BRAF mutation (e.g., a BRAF V600 mutation). In yet other embodiments, the anti-LAG-3 antibody molecule is administered after treatment with an anti-CTLA4 antibody (e.g., ipilimumab) with or without a BRAF inhibitor (e.g., vemurafenib or dabrafenib).

Methods and compositions disclosed herein are useful for treating metastatic lesions associated with the aforementioned cancers.

Exemplary non-limiting combinations and uses of the anti-LAG-3 antibody molecules are disclosed in US 2015/0259420 (U.S. Ser. No. 14/657,260), entitled “Antibody Molecules to LAG-3 and Uses Thereof,” incorporated by reference in its entirety.

In certain embodiments, the combination includes an anti-LAG-3 antibody molecule in combination with a modulator of a costimulatory molecule or an inhibitory molecule, e.g., a coinhibitory ligand or receptor.

In one embodiment, the anti-LAG-3 antibody molecule is administered in combination with a modulator, e.g., agonist, of a costimulatory molecule. In one embodiment, the agonist of the costimulatory molecule is chosen from an agonist (e.g., an agonistic antibody or soluble fusion) of OX40, CD2, CD27, CDS, ICAM-1, LFA-1 (CD11a/CD18), ICOS (CD278), 4-1BB (CD137), GITR, CD30, CD40, BAFFR, HVEM, CD7, LIGHT, NKG2C, SLAMF7, NKp80, CD160, B7-H3, or CD83 ligand.

In another embodiment, the anti-LAG-3 antibody molecule is used in combination with a costimulatory molecule, e.g., an agonist associated with a positive signal that includes a costimulatory domain of CD28, CD27, ICOS and GITR.

In one embodiment, the anti-LAG-3 antibody molecule is administered in combination with an inhibitor of an inhibitory molecule (e.g., an inhibitor of an immune checkpoint molecule). It will be understood by those of ordinary skill in the art, that the term “immune checkpoints” means a group of molecules on the cell surface of CD4 and CD8 T cells. These molecules can effectively serve as “brakes” to down-modulate or inhibit an anti-tumor immune response. Immune checkpoint molecules include, but are not limited to, Programmed Death 1 (PD-1), Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4), B7H1, B7H4, OX-40, CD137, CD40, and TIM-3, which directly inhibit immune cells, immunotherapeutic agents which can act as immune checkpoint inhibitors useful in the methods of the present invention, include, but are not limited to, inhibitors of PD-1, PD-L1, PD-L2, CTLA-4, TIM-3, VISTA, BTLA, TIGIT, LAIR1, CD160, 2B4, CEACAM (e.g., CEACAM-1 and/or CEACAM-5), and/or TGF beta. Inhibition of an inhibitory molecule can be performed by inhibition at the DNA, RNA or protein level. In embodiments, an inhibitory nucleic acid (e.g., a dsRNA, siRNA or shRNA), can be used to inhibit expression of an inhibitory molecule. In other embodiments, the inhibitor of an inhibitory signal is, a polypeptide e.g., a soluble ligand, or an antibody or antibody fragment, that binds to the inhibitory molecule. Exemplary TIM-3 antibody molecules include, but are not limited to, MBG220, MBG227, and MBG219. Exemplary TIGIT inhibitors include, but are not limited to, 10A7 and 1F4 (Roche).

Further examples of modulators include but are not limited to B7-H5, ENTPD1, ENTPD2, SIGGIR, B7-1, B7-2, VSIG4, TIM-1, CD200, RANKL, and P2X7.

In one embodiment, the inhibitor is a soluble ligand (e.g., a CTLA-4-Ig or a TIM-3-Ig), or an antibody or antibody fragment that binds to PD-L1, PD-L2 or CTLA4. For example, the anti-LAG-3 antibody molecule can be administered in combination with an anti-CTLA-4 antibody, e.g., ipilimumab. Exemplary anti-CTLA4 antibodies include Tremelimumab (IgG2 monoclonal antibody available from Pfizer, formerly known as ticilimumab, CP-675,206); and Ipilimumab (CTLA-4 antibody, also known as MDX-010, CAS No. 477202-00-9). In one embodiment, the anti-LAG-3 antibody molecule is administered after treatment, e.g., after treatment of a melanoma, with an anti-CTLA4 antibody (e.g., ipilimumab) with or without a BRAF inhibitor (e.g., vemurafenib or dabrafenib). In one embodiment, the anti-CTLA-4 antibody, e.g., ipilimumab, is administered at a dose of about 3 mg/kg. The anti-LAG-3 antibody molecule can be administered in combination at a dose from about 20 to 800 mg, e.g., about 20, 80, 240, or 800 mg. In one embodiment, the anti-LAG-3 antibody molecule is administered every 2 weeks (e.g., during weeks 1, 3, 5, 7) during each 8 week cycle, e.g., up to 96 weeks.

In another embodiment, the anti-LAG-3 antibody molecule is administered in combination with an anti-PD-1 antibody molecule. Exemplary doses that can be use include a dose of anti-PD-1 antibody molecule of about 1 to 10 mg/kg, e.g., 3 mg/kg. The anti-LAG-3 antibody molecule can be administered in combination at a dose from about 20 to 800 mg, e.g., about 20, 80, 240, or 800 mg. In one embodiment, the anti-LAG-3 antibody molecule is administered every 2 weeks (e.g., during weeks 1, 3, 5, 7) during each 8 week cycle, e.g., up to 96 weeks.

Immune inhibitory molecules, e.g., PD-1 and LAG-3, can regulate, e.g., synergistically, T-cell function to promote tumoral immune escape. In another embodiment, the anti-LAG-3 antibody molecule is administered in combination with an anti-TIM-3 antibody molecule. In still another embodiment, the anti-LAG-3 antibody molecule is administered in combination with an anti-PD-L1 antibody molecule. In yet other embodiments, the anti-LAG-3 antibody molecule is administered in combination with an anti-PD-1 antibody and an anti-TIM-3 antibody. In certain embodiments, the anti-LAG-3 antibody molecule is administered in combination with an anti-PD-1 antibody and an anti-PD-L1 antibody. In certain embodiments, the anti-LAG-3 antibody molecule is administered in combination with an anti-TIM-3 antibody and an anti-PD-L1 antibody. The combination of antibodies recited herein can be administered separately, e.g., as separate antibodies, or linked, e.g., as a bispecific or trispecific antibody molecule. In another embodiment, the anti-LAG-3 antibody molecule is administered in combination with a CEACAM inhibitor (e.g., CEACAM-1 and/or CEACAM-5 inhibitor), e.g., an anti-CEACAM antibody molecule. In another embodiment, the anti-LAG-3 antibody molecule, is administered in combination with a CEACAM-1 inhibitor, e.g., an anti-CEACAM-1 antibody molecule. In another embodiment, the anti-LAG-3 antibody molecule is administered in combination with a CEACAM-5 inhibitor, e.g., an anti-CEACAM-5 antibody molecule. In one embodiment, a bispecific antibody that includes an anti-LAG-3 antibody molecule and an anti-PD-1 or anti-LAG-3 antibody is administered. In certain embodiments, the combination of antibodies recited herein is used to treat a cancer, e.g., a cancer as described herein (e.g., a solid tumor). The efficacy of the aforesaid combinations can be tested in animal models known in the art. For example, the animal models to test the synergistic effect of anti-LAG-3 and anti-PD-1 are described, e.g., in Woo et al. (2012) Cancer Res. 72(4):917-27).

In one embodiment, the inhibitor of CEACAM (e.g., CEACAM-1 and/or CEACAM-5) is an anti-CEACAM antibody molecule. Without wishing to be bound by theory, CEACAM-1 has been described as a ligand and partner of TIM-3 (see e.g., WO 2014/022332). Synergistic in vivo effect of the combination of anti-TIM-3 and anti-CEACAM-1 antibodies have been detected in xenograft cancer models (see e.g., WO 2014/022332). Tumors are believed to use CEACAM-1 or CEACAM-5 to inhibit the immune system, as described in, e.g., Markel et al. J Immunol. 2002 Mar. 15; 168(6):2803-10; Markel et al. J Immunol. 2006 Nov. 1; 177(9):6062-71; Markel et al. Immunology. 2009 February; 126(2):186-200; Markel et al. Cancer Immunol Immunother. 2010 February; 59(2):215-30; Ortenberg et al. Mol Cancer Ther. 2012 June; 11(6):1300-10; Stern et al. J Immunol. 2005 Jun. 1; 174(11):6692-701; Zheng et al. PLoS One. 2010 Sep. 2; 5(9). pii: e12529. Thus, CEACAM inhibitors can be used with the other immunomodulators described herein (e.g., anti-LAG-3, anti-PD-1, or anti-TIM-3 inhibitors) to enhance an immune response against a cancer, e.g., melanoma, lung cancer (e.g., NSCLC), bladder, colon or ovarian cancer, or other cancers as described herein. In one embodiment, the inhibitor of CEACAM is an anti-CEACAM-1 antibody as described in WO 2010/125571, WO 2013/82366 and WO 2014/022332, e.g., a monoclonal antibody 34B1, 26H7, and 5F4 or a recombinant form thereof, as described in, e.g., US 2004/0047858, U.S. Pat. No. 7,132,255 and WO 99/52552. In other embodiments, the anti-CEACAM antibody is an anti-CEACAM-1 and/or anti-CEACAM-5 antibody molecule as described in, e.g., WO 2010/125571, WO 2013/054331 and US 2014/0271618.

In some embodiments, the LAG-3 and PD-1 immune inhibitory molecules (e.g., antibody molecules) are administered in combination with each other, e.g., to treat cancer. In some embodiments, the patient is a patient who progressed (e.g., experienced tumor growth) during therapy with a PD-1 inhibitor (e.g., an antibody molecule as described herein) and/or a PD-L1 inhibitor (e.g., antibody molecule). In some embodiments, therapy with the PD-1 antibody molecule and/or PDL1 antibody molecule is continued, and a LAG-3 immune inhibitory molecule (e.g., antibody) is added to the therapy. In other embodiments, the anti-LAG-3 antibody molecule is administered in combination with a cytokine, e.g., interleukin-21, interleukin-2, or interleukin 15. In certain embodiments, the combination of anti-LAG-3 antibody molecule and cytokine described herein is used to treat a cancer, e.g., a cancer as described herein (e.g., a solid tumor or melanoma).

Exemplary immunomodulators that can be used in combination with the anti-LAG-3 antibody molecules include, but are not limited to, e.g., afutuzumab (available from Roche®); pegfilgrastim (Neulasta®); lenalidomide (CC-5013, Revlimid®); thalidomide (Thalomid®), actimid (CC4047); and cytokines, e.g., IL-21 or IRX-2 (mixture of human cytokines including interleukin 1, interleukin 2, and interferon γ, CAS 951209-71-5, available from IRX Therapeutics).

Another example of such a combination is an anti-LAG-3 antibody in combination with decarbazine for the treatment of melanoma. Another example of such a combination is an anti-LAG-3 antibody molecule in combination with interleukin-2 (IL-2) for the treatment of melanoma. In one embodiment the anti-LAG-3 antibody molecule can be combined with IL-21. Without being bound by theory, the combined use of LAG-3 blockade and chemotherapy is that cell death, is believed to be facilitated by cell death, that is a consequence of the cytotoxic action of most chemotherapeutic compounds, which can result in increased levels of tumor antigen in the antigen presentation pathway. Other combination therapies that may result in synergy with LAG-3 blockade through cell death are radiation, surgery, and hormone deprivation. Each of these protocols creates a source of tumor antigen in the host. Angiogenesis inhibitors may also be combined with LAG-3 blockade. Inhibition of angiogenesis leads to tumor cell death which may feed tumor antigen into host antigen presentation pathways.

Combinations that include LAG-3 blocking antibodies can also be used in combination with bispecific antibodies. Bispecific antibodies can be used to target two separate antigens. For example anti-Fc receptor/anti tumor antigen (e.g., Her-2/neu) bispecific antibodies have been used to target macrophages to sites of tumor. This targeting may more effectively activate tumor specific responses. The T cell arm of these responses would by augmented by the use of LAG-3 blockade. Alternatively, antigen may be delivered directly to DCs by the use of bispecific antibodies which bind to tumor antigen and a dendritic cell specific cell surface marker.

Tumors evade host immune surveillance by a large variety of mechanisms. Many of these mechanisms may be overcome by the inactivation of proteins which are expressed by the tumors and which are immunosuppressive. These include among others TGF-beta (Kehrl, J. et al. (1986) J. Exp. Med. 163: 1037-1050), IL-10 (Howard, M. & O'Garra, A. (1992) Immunology Today 13: 198-200), and Fas ligand (Hahne, M. et al. (1996) Science 274: 1363-1365). Antibodies to each of these entities may be used in combination with anti-LAG-3 to counteract the effects of the immunosuppressive agent and favor tumor immune responses by the host.

Other antibodies which may be used to activate host immune responsiveness can be used in the combinations herein further in combination with an anti-LAG-3 antibody molecule, e.g., an anti-LAG-3 antibody molecule as described herein. These include molecules on the surface of dendritic cells which activate DC function and antigen presentation. Anti-CD40 antibodies are able to substitute effectively for T cell helper activity (Ridge, J. et al. (1998) Nature 393: 474-478) and can be used in conjunction with LAG-3 antibodies (Ito, N. et al. (2000) Immunobiology 201 (5) 527-40). Activating antibodies to T cell costimulatory molecules such as CTLA-4 (e.g., U.S. Pat. No. 5,811,097), OX-40 (Weinberg, A. et al. (2000) Immunol 164: 2160-2169), 4-1BB (Melero, I. et al. (1997) Nature Medicine 3: 682-685 (1997), and ICOS (Hutloff, A. et al. (1999) Nature 397: 262-266) may also provide for increased levels of T cell activation.

Additional exemplary standard of care treatments are described in the section entitled “Combination Therapies” in US 2015/0259420 (U.S. Ser. No. 14/657,260), entitled “Antibody Molecules to LAG-3 and Uses Thereof,” incorporated by reference in its entirety, and below.

In all of the methods described herein, LAG-3 blockade can be combined with other forms of immunotherapy such as cytokine treatment (e.g., interferons, GM-CSF, G-CSF, IL-2, IL-21), or bispecific antibody therapy, which provides for enhanced presentation of tumor antigens (see, e.g., Holliger (1993) Proc. Natl. Acad. Sci. USA 90:6444-6448; Poljak (1994) Structure 2:1121-1123).

This disclosure also provides a method of treating cancer with Compound A8, cetuximab, and a LAG-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or TIM-3 antibody molecule). In some embodiments, the patient is first treated with Compound A8 and cetuximab. This treatment continues for an amount of time, e.g., a predetermined amount of time, e.g., about 1, 2, 4, 6, 8, 10, or 12 months. Next, the LAG-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or TIM-3 antibody molecule) is administered. The LAG-3 antibody can optionally be administered in combination with cetuximab.

In some embodiments, the patient is first treated with all three of Compound A8, cetuximab, and a LAG-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or TIM-3 antibody molecule). This treatment continues for an amount of time, e.g., a predetermined amount of time, e.g., about 6, 8, 10, or 12 months. Next, the Compound A8 and/or cetuximab can be tapered off, so that the maintenance phase involves treatment with the LAG-3 antibody molecule (e.g., as a monotherapy, or in combination with a PD-1 antibody molecule or TIM-3 antibody molecule) but not Compound A8 or cetuximab.

In other embodiments, the three compounds (Compound A8, cetuximab, and a LAG-3 antibody molecule, optionally in combination with a PD-1 antibody molecule or TIM-3 antibody molecule) are given sequentially at the outset of the treatment. For instance, Compound A8 and cetuximab can be given first, as described above. Next, the LAG-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or TIM-3 antibody molecule) is added to the regimen. Next, the Compound A8 and/or cetuximab can be tapered off as described above.

Exemplary doses for the three (or more) agent regimens are as follows. The LAG-3 antibody molecule can be administered, e.g., at a dose of about 1 to 40 mg/kg, e.g., 1 to 30 mg/kg, e.g., about 5 to 25 mg/kg, about 10 to 20 mg/kg, about 1 to 5 mg/kg, or about 3 mg/kg. In some embodiments, the Compound A8 is administered at a dose of approximately 200-300, 300-400, or 200-400 mg. In some embodiments, the cetuximab is administered at a 400 mg/m2 initial dose as a 120-minute intravenous infusion followed by 250 mg/m2 weekly infused over 60 minutes. In embodiments, one or more of the Compound A8, cetuximab, and LAG-3 antibody molecule is administered at a dose that is lower than the dose at which that agent is typically administered as a monotherapy, e.g., about 0-10%, 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower than the dose at which that agent is typically administered as a monotherapy. In embodiments, the one or more of the Compound A8, cetuximab, and LAG-3 antibody molecule is administered at a dose that is lower than the dose of that agent recited in this paragraph, e.g., about 0-10%, 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower than the dose of that agent recited in this paragraph. In certain embodiments, the concentration of the Compound A8 that is required to achieve inhibition, e.g., growth inhibition, is lower when the Compound A8 is administered in combination with one or both of the cetuximab and LAG-3 antibody molecule than when the Compound A8 is administered individually. In certain embodiments, the concentration of the cetuximab that is required to achieve inhibition, e.g., growth inhibition, is lower when the cetuximab is administered in combination with one or both of the Compound A8 and LAG-3 antibody molecule than when the cetuximab is administered individually. In certain embodiments, the concentration of the LAG-3 antibody molecule that is required to achieve inhibition, e.g., growth inhibition, is lower when the LAG-3 antibody molecule is administered in combination with one or both of the cetuximab and Compound A8 than when the LAG-3 antibody molecule is administered individually.

Additionally disclosed herein is a method of treating cancer with the anti-LAG-3 antibody molecules, alone or in combination with another immunomodulator (e.g., an anti-PD-1, anti-PD-L1 or anti-TIM-3 antibody molecule), and a targeted anti-cancer agent, e.g., an agent that targets one or more proteins. In some embodiments, the anti-LAG-3 antibody molecule (and optionally other immunomodulator(s)) are administered first, and the targeted anti-cancer agent is administered second. The length of time between administration of the anti-LAG-3 antibody molecule and the targeted anti-cancer agent can be, e.g., 10, 20, or 30 minutes, 1, 2, 4, 6, or 12 hours, or 1, 2, 3, 4, 5, 6, or 7 days, or any span of time within this range. In certain embodiments, the anti-LAG-3 antibody molecule is administered repeatedly over a period of time (e.g., 1, 2, 3, 4, 5, or 6 days, or 1, 2, 4, 8, 12, 16, or 20 weeks, or any span of time within this range) before the targeted anti-cancer agent is administered. In other embodiments, the anti-LAG-3 antibody molecule and the targeted anti-cancer agent are administered at substantially the same time.

Infectious Diseases

Other methods of the invention are used to treat patients that have been exposed to particular toxins or pathogens. Accordingly, another aspect of the invention provides a method of treating an infectious disease in a subject comprising administering to the subject a combination as disclosed herein, e.g, a combination including an anti-LAG-3 antibody molecule, such that the subject is treated for the infectious disease.

In the treatment of infection (e.g., acute and/or chronic), administration of the anti-LAG-3 antibody molecules (alone or in combination with an anti-PD-1, anti-PD-L1 or anti-TIM-3 antibody molecule) can be combined with conventional treatments in addition to or in lieu of stimulating natural host immune defenses to infection. Natural host immune defenses to infection include, but are not limited to inflammation, fever, antibody-mediated host defense, T-lymphocyte-mediated host defenses, including lymphokine secretion and cytotoxic T-cells (especially during viral infection), complement mediated lysis and opsonization (facilitated phagocytosis), and phagocytosis. The ability of the anti-LAG-3 antibody molecules to reactivate dysfunctional T-cells would be useful to treat chronic infections, in particular those in which cell-mediated immunity is important for complete recovery.

Similar to its application to tumors as discussed above, antibody mediated LAG-3 blockade can be used alone, or as an adjuvant, in combination with vaccines, to stimulate the immune response to pathogens, toxins, and self-antigens. Examples of pathogens for which this therapeutic approach may be particularly useful, include pathogens for which there is currently no effective vaccine, or pathogens for which conventional vaccines are less than completely effective. These include, but are not limited to Hepatitis (A, B, and C), Influenza, HIV, Herpes, Giardia, Malaria, Leishmania, Staphylococcus aureus, Pseudomonas Aeruginosa. LAG-3 blockade is particularly useful against established infections by agents such as HIV that present altered antigens over the course of the infections. These novel epitopes are recognized as foreign at the time of anti-human LAG-3 administration, thus provoking a strong T cell response that is not dampened by negative signals through LAG-3.

Human Mixed Lymphocyte Reaction

The Mixed Lymphocyte Reaction (MLR) is a functional assay which measures the proliferative response of lymphocytes from one individual (the responder) to lymphocytes from another individual (the stimulator). To perform an allogeneic MLR, peripheral blood mononuclear cells (PBMC) from three donors were isolated from buffy-coats of unknown HLA type (Kantonspital Blutspendezentrum from Bern and Aarau, Switzerland). The cells were prepared at 2×10⁵ in 0.2 mL of culture medium containing RPMI 1640 GlutaMAX™ with 10% fetal calf serum (FCS), 100 U penicillin/100 μg streptomycin, 50 μM 2-Mercaptoethanol. Individual 2-way reactions were set up by mixing PBMC from two different donors at a 1:1 ratio and co-cultures were done in triplicates in flat-bottomed 96-well tissue culture plates for 6 days at 37° C., 5% CO2, in presence or not of an 8-point concentration range of test compounds. Cells were pulsed with 3H-TdR (1 μCi/0.2 mL) for the last 16 h of culture and incorporated radioactivity was used as a measure of cell proliferation. The concentration that inhibited 50% of the maximal huMLR response (IC50) was calculated for each compound. Cyclosporine was used as a positive control of huMLR inhibition.

Human B Cell Proliferation Assay

PBMC were freshly isolated by Ficoll-Paque density gradient from human blood and subjected to negative B-cell isolation. B cells were resuspended in culture medium (RPMI 1640, HEPES, 10% FCS, 50 μg/mL gentamicine, 50 μM 2-Mercaptoethanol, lx ITS (Insulin, Transferrin and Sodium Selenite), lx Non-Essential Amino-Acids) at a concentration of 9.104 per well in a flat-bottom 96-well culture plate.

In another aspect, the application features host cells and vectors containing the nucleic acids described herein. The nucleic acids may be present in a single vector or separate vectors present in the same host cell or separate host cell, as described in more detail hereinbelow.

Vectors

Further provided herein are vectors comprising nucleotide sequences encoding an antibody molecule described herein. In one embodiment, the vectors comprise nucleotides encoding an antibody molecule described herein. In one embodiment, the vectors comprise the nucleotide sequences described herein. The vectors include, but are not limited to, a virus, plasmid, cosmid, lambda phage or a yeast artificial chromosome (YAC).

Numerous vector systems can be employed. For example, one class of vectors utilizes DNA elements which are derived from animal viruses such as, for example, bovine papilloma virus, polyoma virus, adenovirus, vaccinia virus, baculovirus, retroviruses (Rous Sarcoma Virus, MMTV or MOMLV) or SV40 virus. Another class of vectors utilizes RNA elements derived from RNA viruses such as Semliki Forest virus, Eastern Equine Encephalitis virus and Flaviviruses.

Additionally, cells which have stably integrated the DNA into their chromosomes may be selected by introducing one or more markers which allow for the selection of transfected host cells. The marker may provide, for example, prototropy to an auxotrophic host, biocide resistance, (e.g., antibiotics), or resistance to heavy metals such as copper, or the like. The selectable marker gene can be either directly linked to the DNA sequences to be expressed, or introduced into the same cell by cotransformation. Additional elements may also be needed for optimal synthesis of mRNA. These elements may include splice signals, as well as transcriptional promoters, enhancers, and termination signals.

Once the expression vector or DNA sequence containing the constructs has been prepared for expression, the expression vectors may be transfected or introduced into an appropriate host cell. Various techniques may be employed to achieve this, such as, for example, protoplast fusion, calcium phosphate precipitation, electroporation, retroviral transduction, viral transfection, gene gun, lipid based transfection or other conventional techniques. In the case of protoplast fusion, the cells are grown in media and screened for the appropriate activity.

Methods and conditions for culturing the resulting transfected cells and for recovering the antibody molecule produced are known to those skilled in the art, and may be varied or optimized depending upon the specific expression vector and mammalian host cell employed, based upon the present description.

EXAMPLES

The Examples below are set forth to aid in the understanding of the inventions but are not intended to, and should not be construed to, limit its scope in any way.

Example 1: Humanization of Anti-LAG-3 Antibody, BAP050

A murine anti-LAG-3 monoclonal antibody, BAP050, was humanized. The sequences and test samples of twenty humanized BAP050 clones with unique variable region sequences were obtained. These clones were further analyzed for their biological functions (e.g., antigen binding and ligand blocking), structural features, and transient expression in CHO cells.

Example 1.1: Humanization Technology and Process

Humanization of BAP050 was performed using a combinatorial library of human germ line variable region frameworks (FWs). The technology entails transferring the murine CDRs in frame to a library of human variable regions (VRs) that had been constructed by randomly combining human germ line FW1, FW2 and FW3 sequences. Only one FW4 sequence is used, which is WGQGTTVTVSS (SEQ ID NO: 221) for the heavy chain (HC) (Kabat human HC subgroup I, No. 21) and FGQGTKVEIK (SEQ ID NO: 271) for the light chain (LC) (Kabat human κ subgroup I, No. 5). The library of VR sequences is fused to human constant region (CR) sequences, human IgG4(S228P) of HC and human κ CR of LC, and the resulting library of whole IgG is expressed in CHO cells for screening. Screening was performed with tissue culture supernatants measuring binding avidity on antigen-expressing cells in a whole cell ELISA format or on FACS.

The humanization process was performed in a stepwise manner starting with the construction and expression of the appropriate chimeric mAb (murine VR, IgG4(S228P), human κ), which can serve as a comparator for the screening of the humanized clones. The constant region amino acid sequences for human IgG4(S228P) heavy chain and human kappa light chain are shown in Table 6.

Humanization of the VR of LC and HC were performed in two independent steps. The library of humanized LC (huLC) was paired with the chimeric HC (murine VR, IgG4(S228P)) and the resulting “half-humanized” mAbs were screened for binding activity by ELISA. The huLC of clones with adequate binding activity (≥binding of chimeric mAb) were selected. Analogously, the library of humanized HC (huHC) was paired with the chimeric LC (murine VR, human κ) and screened for binding activity by ELISA. The huHC of clones with appropriate binding activity (≥binding of chimeric mAb) were selected.

The variable regions of the selected huLC and huHC were then sequenced to identify the huLC and huHC with unique sequences (some clones from the initial selection process may share the same LC or HC). The unique huLC and huHC were then randomly combined to form a small library of humAbs, which was expressed in CHO cells and screened on antigen-expressing cells in an ELISA and FACS format. Clones with binding activities that were equal or better than the binding of the chimeric comparator mAb are the final product of the humanization process.

Example 1.2: Sequence of Murine mAb BAP050

The LC and HC variable region sequences of the murine anti-LAG-3 mAb were determined. The sequences obtained from two independent analyses were identical and are shown in FIG. 1.

Germline analysis was performed and part of the result is shown in FIG. 2 as an amino acid sequence alignment. For the light chain, the V-gene is 96.88% identical to mIGkV10-94*01F (279/288 nts) and the J-gene is 97.30% identical to mlGkJ1*01F (36/37 nts). For the heavy chain, the V-gene is 96.88% identical to mIGHV9-3-1*01F (279/288 nts), the J-gene is 86.79% identical to mIGHJ4*01F, and the D-gene is mIGHD1-1*01F.

Example 1.3: Humanized Antibody Clones

As shown in FIG. 3, the process of humanization yielded twenty humanized clones with binding affinities comparable to that of the chimeric antibody. In addition to binding data, for each clone, the VR sequences were provided along with a sample of the mAb. The samples had been prepared by transient transfections of CHO cells and were concentrated tissue culture supernatants. The mAb concentrations in the solutions had been determined by an IgG4-specific ELISA.

As shown in FIG. 4, the twenty unique clones are combinations of six unique HC and twelve unique LC. The amino acid and nucleotide sequences of the heavy and light chain variable domains for the humanized BAP050 clones are shown in Table 1. The amino acid and nucleotide sequences of the heavy and light chain CDRs of the humanized BAP050 clones are shown in Table 1.

Limited diversity was obtained for the HC FW3 region with eighteen clones having the same FWH3, which is from the human germ line IGHV7-4 and has an exposed Cys residue at position 84 of the humanized clones. Closely related VHFW3 sequences typically have a Ser or Ala residue in this position. Therefore, Cys84 was replaced by Ser in selected humanized clones.

FIG. 4 indicates that the samples varied in the concentration of the mAb, ranging from 3.2 μg/mL to 35.8 μg/mL. These numbers were representative of several transient expression experiments.

Example 1.4: Analysis of the Humanized Clones Example 1.4.1: Analysis of Binding Activity and Binding Specificity of Humanized Clones

The binding activity and specificity was measured in a competition binding assay using a constant concentration of FITC-labeled murine mAb, serial dilutions of the test mAbs, and LAG-3-expressing CHO cells. Incubations with the mAb mixtures having different concentration ratios of test mAb to labeled mAb was at 4° C. for 30 min. Bound labeled murine mAb was then quantified using a FACS machine. The experiment was performed twice. The results are shown in FIGS. 5A-5B.

Within the accuracy of the experiment, all humanized clones show similar activity for competing with binding of labeled murine mAb. The activity is also comparable to the activity of the parent murine mAb and chimeric mAb. MAbs were ranked relative to each other. For example, it can be a weaker competitor if in both experiments the curve of a certain clone is to the right of the chimeric mAb curve or it can be a better competitor if the curve of a certain clone is to the left of the chimeric mAb curve. Such a ranking system was used in FIG. 6.

Example 1.4.2: Sequence Analysis of Humanized Clones

Based on structural features, the twenty humanized mAbs were divided into six groups and ranked them from A to F. The results are shown in FIG. 6.

Example 1.4.3: Selection of Humanized Clones and Generation of New Versions with the C84S Mutation

FIG. 6 summarizes the data which was considered for the selection of humanized clones. Expression data (2^(nd) column), the diversity in the composition of the variable regions (3^(rd) column), relative rankings in binding studies (4^(th) and 5^(th) columns), and structural analysis (6^(th) column), were considered. Certain characteristics that lead to the selection of individual clones are marked with grey fields.

Certain clones were mutated at position 84 of VHFW3 from Cys to Ser (see Example 1.3 above). The new versions are called clones Nos. 1S, 2S, 5S, 9S, 11S, 125, and 135, and together huBAP050(Ser) clones.

The new versions of the selected clones with the C84S mutation in VHFW3 were subject to an analogous competition binding assay as described under Example 1.4.1. The experiment included the original humanized clones with the Cys84 residue, the new humanized clones with the Ser84 residue, chimeric mAb and the parent murine mAb. The results are shown in FIG. 7.

All tested variants were comparable to the murine parent mAb in blocking the binding of labeled murine mAb to LAG-3-expressing CHO cells. It follows that the behavior of the new humanized clones with the Ser84 residue was not different from the behavior of the original humanized clones with the Cys84 residue.

Example 1.4.5: Blocking of Binding of LAG-3-Ig to MHC Class II on Daudi Cells

LAG-3 binds to MHC class II, therefore the selected huBAP050(Ser) clones were tested for their ability to block the binding of soluble LAG-3-Ig to Daudi cells (a Burkitt's lymphoma cell line) that express MHC class II. The blocking capacity of the mAbs was evaluated in a competition binding assay using a constant concentration of LAG-3-huIgG1 Fc fusion protein (2 μg/mL), serial dilutions of the mAbs to be tested, and Daudi cells. Incubation was at 4° C. for 30 min. Bound ligand fusion protein was detected with PE-conjugated F(ab′)2 fragment of goat anti-human IgG which doesn't recognize IgG4 mAbs (Southern Biotech 2043-09), and flow cytometry. The results are shown in FIG. 8.

Within the accuracy of the experiments, the seven huBAP050(Ser) clones, chimeric mAb and murine parent mAb demonstrated comparable blocking activity for LAG-3-Ig.

Example 1.4.6: T Cell Epitope Analysis

Humanized mAbs were analyzed for T cell epitopes using Epibase™. The algorithm analyzes each possible peptide (each 10-mer along the protein advancing by one amino acid) for binding to HLA class II. It estimates free energy of binding (ΔG_(bind)) for each peptide and calculates a putative K_(D) (ΔG_(bind)=RT lnK_(D)). Then peptides are labeled S, M, or N for strong, medium, and non-binders. Threshold values used for this classification are different for each allotype.

The data was normalized to a risk score. The overall “risk score” is the sum of all potential epitopes to all tested alleles, weighted by the affinities of the respective peptides but leaving out all potential epitopes in germ line sequences (lower value therefor is “better”) There are roughly three categories of mAbs, derived from a large set of mAbs of different composition as described below.

Risk score of around 500: fully human mAbs generated from humans, “humanized” mice, and phage libraries (“values below 500 are really good even for fully human antibodies”).

Humanized mAbs specifically engineered (even the CDRs) to have a low score are typically in the 500-700 risk category.

Risk score around 900: typical CDR-grafted antibodies, which have fully murine CDRs with or without changes in the FW region (“Gary Queen technology”); approved CDR-grafted mAbs are basically all in this category.

Risk score around 1500: chimeric mAbs.

The results for selected humanized BAP050 mAbs are:

Clone No. Risk score 01 999 02 1006 05 967 09 998 11 1042 12 1042 13 950

The risk scores of the seven selected humanized clones are in the typical CDR-grafted mAb category. For example, the human mAb, adalimumab (Humira®), has a score of 654, which is relatively high for human mAbs (at the upper end of the Gaussian curve) but low in comparison to a typical CDR-grafted mAb.

The scores come from the murine CDRs, specifically the Y residues. These are acceptable scores for antibodies for cancer treatment. Changing the score would mean engineering the murine CDRs, specifically removing Y residues.

Summary and Conclusions

Murine anti-LAG-3 monoclonal antibody, BAP050, was humanized. The technology entails the cloning of the murine CDRs in-frame into an ordered library of human germ line variable region frameworks, expressing the library of cloned variable regions as intact IgG4(S228P) humanized mAbs in CHO cells, and selecting clones that bind with comparable or higher affinity to the target as the parent mAb. Therefore, the murine CDRs were asked to select the best human germ line framework sequences that preserve their conformations and thus the binding affinity and specificity of the parent murine mAb. The sequences and test samples of twenty humanized versions with unique variable region sequences were obtained, which had also passed a binding test with LAG-3-transfected CHO cells. Eighteen clones contained the same HC FW3 germ line sequence, which has a rare Cys at position 84. In seven selected clones, Cys was replaced by Ser creating new mAbs labeled huBAP050(Ser) clones. These clones were further analyzed for their biological functions (e.g., antigen binding and ligand blocking), structural features, and transcient expression in CHO cells.

Example 2: Expression of Humanized Anti-LAG-3 Antibody, BAP050

Five humanized clones described in Example 1 were selected for evaluation of expression in Chinese Hamster Ovary (CHO) cells.

Single gene vectors (SGVs) were constructed using Lonza's GS Xceed vectors (IgG4proΔk for heavy chain and Kappa for light chain). The SGVs were amplified and transiently co-transfected into CHOK1SV GS-KO cells for expression at a volume of 2.8 L.

Expression cultures were harvested Day 6 post-transfection and clarified by centrifugation and sterile filtration. The clarified cell culture supernatant was purified using one-step Protein A chromatography. Product quality analysis in the form of SE-HPLC, SDS-PAGE, IEF, and LAL was carried out using purified material at a concentration of 1 mg/ml including an antibody as a control sample.

Example 2.1: Vector Construction

The sequences of the light and heavy chain variable domain encoding regions were synthesised by GeneArt AG. Light chain variable domain encoding regions were sub-cloned into pXC-Kappa and heavy chain variable domain encoding regions into pXC-IgG4pro ΔK vectors respectively using the N-terminal restriction site Hind III and the C-terminal restriction sites BsiWI (light chain) and ApaI (heavy chain). Positive clones were screened by PCR amplification (primers 1053: GCTGACAGACTAACAGACTGTTCC (SEQ ID NO: 288) and 1072: CAAATGTGGTATGGCTGA (SEQ ID NO: 289)) and verified by restriction digest (using a double digest of EcoRI-HF and HindIII-HF) and nucleotide sequencing of the gene of interest.

Example 2.2: DNA Amplification

A single bacterial colony was picked into 15 ml Luria Bertani (LB) medium (LB Broth, Sigma-Aldrich, L7275) containing 50 μg/ml ampicillin and incubated at 37° C. overnight with shaking at 220 rpm. The resulting starter culture was used to inoculate 1 L Luria Bertani (LB) medium containing 50 μg/ml ampicillin and incubated at 37° C. overnight with shaking at 220 rpm. Vector DNA was isolated using the QIAGEN Plasmid Plus Gigaprep system (QIAGEN, 12991). In all instances, DNA concentration was measured using a Nanodrop 1000 spectrophotometer (Thermo-Scientific) and adjusted to 1 mg/ml with EB buffer (10 mM Tris-C1, pH 8.5). DNA quality for the single gene vectors was assessed by measuring the absorbance ratio A260/A280. This was found to be between 1.88 and 1.90.

Example 2.3: Culture of CHOK1SV GS-KO Cells

CHOK1SV GS-KO cells were cultured in CD-CHO media (Invitrogen, 10743-029) supplemented with 6 mM glutamine (Invitrogen, 25030-123). Cells were incubated in a shaking incubator at 36.5° C., 5% CO₂, 85% humidity, 140 rpm. Cells were routinely sub-cultured every 3-4 days, seeding at 2×10⁵ cells/ml and were propagated in order to have sufficient cells available for transfection. Cells were discarded by passage 20.

Example 2.4: Transient Transfections of CHOK1SV GS-KO Cells

Transient transfections were performed using CHOK1SV GS-KO cells which had been in culture a minimum two weeks. Cells were sub-cultured 24 h prior to transfection and cell viability was >99% at the time of transfection.

All transfections were carried out via electroporation using a Gene Pulse MXCell (Bio-Rad), a plate based system for electroporation. For each transfection, viable cells were resuspended in pre-warmed media to 2.86×10⁷ cells/ml. 80 μg DNA (1:1 ratio of heavy and light chain SGVs) and 700 μl cell suspension were aliquotted into each cuvette/well. Cells were electroporated at 300 V, 1300 μF. Transfected cells were transferred to pre-warmed media in Erlenmeyer flasks and the cuvette/wells rinsed twice with pre-warmed media which was also transferred to the flasks. Transfected cell cultures were incubated in a shaking incubator at 36.5° C., 5% CO₂, 85% humidity, 140 rpm for 6 days. Cell viability and viable cell concentrations were measured at the time of harvest using a Cedex HiRes automated cell counter (Roche).

Example 2.5: Protein A Affinity Chromatography

Cell culture supernatant was harvested and clarified by centrifugation at 2000 rpm for 10 min, then filtered through a 0.22 μm PES membrane filter. Clarified supernatant was purified using a pre-packed 5 ml HiTrap MabSelect SuRE column (GE Healthcare, 11-0034-94) on an AKTA purifier (10 ml/min). The column was equilibrated with 50 mM sodium phosphate, 125 mM sodium chloride, pH 7.0 (equilibration buffer) for 5 column volumes (CVs). After sample loading, the column was washed with 2 CVs of equilibration buffer followed by 3 CVs of 50 mM sodium phosphate, 1 M sodium chloride pH 7.0 and a repeat wash of 2 CVs of equilibration buffer. The Product was then eluted with 10 mM sodium formate, pH 3.5 over 5 CVs. Protein containing, eluted fractions were immediately pH adjusted to pH 7.2 and filtered through a 0.2 am filter.

A single protein-containing peak was observed during the elution phase. This peak was shown to contain the mAb, when analyzed by SE-HPLC and SDS-PAGE. Recovered protein yield is shown in Table 5. The clones expressed transiently in a range from 21.9 to 29.4 mg/L.

Example 2.6: SE-HPLC Analysis

Samples of Protein A purified antibodies were analyzed in duplicate by SE-HPLC on an Agilent 1200 series HPLC system, using a Zorbax GF-250 4 μm 9.4 mm ID×250 mm column (Agilent). Aliquots of sample at a concentration of 1 mg/ml were filtered through a 0.2 m filter prior to injection. 80 μl aliquots were injected respectively and run at 1 ml/min for 15 minutes. Soluble aggregate levels were analysed using Chemstation (Agilent) software.

Chromatography profiles with retention time showing the percentage of the overall detected peak areas were obtained for the tested antibodies and a control IgG4 antibody. The products show a single protein peak at approximately 8.59 to 8.61 min comparable to the human IgG4 antibody control (about 8.64 min) and consistent with a monomeric antibody. Small amounts (up to about 3-4%) of higher molecular weight impurities, consistent with soluble aggregates, were detected at retention times around 7.90 min.

Example 2.7: SDS-PAGE Analysis

Reduced samples were prepared for analysis by mixing with NuPage 4×LDS sample buffer (Invitrogen, NP0007) and NuPage 10× sample reducing agent (Invitrogen, NP0009), and incubated at 70° C., 10 min. For non-reduced samples, the reducing agent and heat incubation were omitted. Samples were electrophoresed on 1.5 mm NuPage 4-12% Bis-Tris Novex pre-cast gels (Invitrogen, NP0335PK2) with NuPage MES SDS running buffer under denaturing conditions. 10 μl aliquots of SeeBlue Plus 2 pre-stained molecular weight standard (Invitrogen, LC5925) and a control IgG4 antibody at 1 mg/ml were included on the gel. 1 μl of each sample at 1 mg/ml were loaded onto the gel. Once electrophoresed, gels were stained with InstantBlue (TripleRed, ISB01L) for 30 min at room temperature. Images of the stained gels were analysed on a BioSpectrum Imaging System (UVP).

The analysis confirmed the presence of the antibody products and good levels of purity. Under non-reducing conditions, a predominant protein band close to 98 kDa was observed comparable with the control IgG4 antibody. The control IgG4 antibody and one tested clone display an additional fainter band corresponding to a heavy plus light chain half-antibody at approximately 70 kDa under non-reducing conditions. This is expected for the control antibody. Two bands were observed under reducing conditions consistent with the size of heavy (close to the position of the 49 kDa marker) and light chains (close to the position of the 28 kDa marker) and comparable with the bands found for the control IgG4 antibody.

Example 2.8: Iso-Electric Focussing (IEF) Analysis

Non-reduced samples of Protein A purified antibody were electrophoresed as described below.

5 μg of Protein A purified samples were electrophoresed on a 1.0 mm Novex pH 3-10 gradient gel (Invitrogen, EC66552BOX) using manufacturers recommended running conditions. A 10 μl aliquot of IEF pH 3-10 markers (Invitrogen, 39212-01) was included on the gel. Once electrophoresed, gels were fixed with 10% TCA solution for 30 min and then stained with InstantBlue (TripleRed, ISB01L) over night at room temperature. Images of the stained gels were analysed on a BioSpectrum Imaging System (UVP).

As shown in Table 6, the tested clones display charge isoforms between pH 6.0 and 7.45. The detected charge isoforms are comparable to the theoretically calculated pIs for these antibodies which were predicted to be between 6.35 and 6.82. Clones F and G both have a predicted pI of 6.35 and show comparable charge isoforms, which is also consistent with the theoretically calculated pI being the same for both (6.35). The control IgG4 antibody behaved as expected.

Example 2.9: Endotoxin Analysis

Endotoxin levels of purified proteins were measured at final concentrations (up to 3.44 mg/ml) using an Endosafe-PTS instrument, a cartridge based method based on the LAL assay (Charles River).

As shown in Table 8, the endotoxin content was found to range from 0.05 to 0.27 EU/mg.

Conclusion

GS single gene expression vectors for selected humanized anti-LAG-3 mAbs were constructed and used to transiently transfect CHOK1SV GS-KO cells. 2.6 to 2.8 litres of expression culture were incubated under standard conditions for 6 days and the resulting cell culture supernatant purified using Protein A chromatography. Post-purification titres are indicated in Table 8 and were found to be ranging from 21.88 to 29.38 mg/L. The recovered yields range from 61.3 to 82.3 mg.

SDS-PAGE and SE-HPLC analysis indicated the presence of a small amount (up to 4.69%) of soluble aggregates present in the products being predominantly consistent with dimeric antibody for the mAb. The mAbs also showed higher molecular weight impurities at retention times consistent with that of trimeric antibodies.

Iso-electric focusing detected a number of charge isoforms for all mAbs. The mAbs showed isoforms generally more basic when based on theoretically calculated pI for these molecules indicating some level of post translation modification. The mAbs were found to be comparable to their theoretically calculated pI values.

The endotoxin levels for all samples were measured prior to provision of samples and found to be below 0.63 EU/mg.

Example 3: Characterization of Murine and Humanized Anti-LAG-3 Antibodies Example 3.1: Characterization of Murine Anti-LAG-3 Antibody

The binding affinity of murine anti-LAG-3 antibody BAP050 to LAG-3 was investigated. As shown by FACS analyses, the murine anti-LAG-3 antibody binds to human LAG-3 transfected CHO cells with a K_(D) of 0.2 nM, to human T cells with a K_(D) of 0.26 nM, and to human LAG-3 transfected 300.19 cells with a K_(D) of 13.6 nM.

The blocking activity of murine anti-LAG-3 antibody BAP050 was examined by competition binding assays. The murine anti-LAG-3 antibody blocked LAG-3-Ig binding to MHC class II molecules on Raji cells with an IC50 of 2.3 nM.

The effect of murine anti-LAG-3 antibody BAP050 on interferon gamma (IFN-γ) expression was tested. The murine anti-LAG-3 antibody resulted in 3.0±2.1 fold increase in IFN-γ expression on cells stimulated with anti-CD3 (0.1 μg/mL), 1.6±0.4 fold increase on cells stimulated with Staphylococcal enterotoxin B (SEB) (3 pg/mL), and 1.4±0.3 fold increase on cells stimulated with CMV peptides.

The regions in LAG-3 that may bind murine anti-LAG-3 antibody BAP050 were examined. As shown by ELISA, the murine anti-LAG-3 antibody binds a LAG-3 Ig fusion protein (sLAG-3 D1-D4Ig) that contains all four extracellular Ig-like domains (D1-D4), as well as a LAG-3 Ig fusion protein (sLAG-3 D1-D2Ig) that only contains Domain 1 (D1) to Domain 2 (D2). Further analysis shows that the anti-LAG-3 antibody binds CHO cells that express full length LAG-3, LAG-3 with D2 deletion (CHO-LAG-3AD2), and LAG-3 with partial deletion of D1 extra loop (CHO-LAG-3AP48A60). Thus, the anti-LAG-3 antibody binds D1 of LAG-3.

The murine anti-LAG-3 antibody BAP050 was also found to increase IFN-γ secretion in CD3-stimulated PBMCs compared to mouse IgG control and no antibody control. The fold of increase ranges from 1.4 to 2.9-fold among four donors.

Example 3.2: Characterization of Humanized Anti-LAG-3 Antibody Binding Affinity and Specificity

The binding of an exemplary humanized anti-LAG-3 antibody on human LAG-3 protein was measured using Biacore method. The results are: Ka=6.41×10⁵ M⁻¹s⁻¹; Kd=7.00×10⁻⁵ s⁻¹; K_(D)=0.109±0.008 nM. The anti-LAG-3 antibody also binds cynomolgus LAG-3 as measured by Biacore method.

The binding of the same humanized anti-LAG-3 antibody on human LAG-3-expressing CHO cells and cynomologous monkey LAG-3 expressing HEK 209 cells. was measured using FACS analysis. The result shows that the anti-LAG-3 antibody (human IgG4) binds with high affinity to human LAG-3 compared to a human IgG4 isotype control. The anti-LAG-3 antibody binds human LAG-3-expressing cells with a K_(D) of 1.92 nM and binds cynomologous monkey LAG-3-expressing cells with a K_(D) of 2.3 nM.

The binding of the anti-LAG-3 antibody on rhesus LAG-3-expressing 300.19 cells was also measured. The results show that the anti-LAG-3 antibody binds rhesus LAG-3 with a K_(D) of 8.03 nM.

Additional binding analyses show that the exemplary humanized anti-LAG-3 antibody is not cross-reactive with mouse LAG-3 or cross-reactive with parental cell line.

Blocking of Interactions Between LAG-3 and its Ligands

The ability of the exemplary humanized anti-LAG-3 antibody to block the interactions between LAG-3 and both of its known ligand, MHC class II molecules, was examined. The results show that the anti-LAG-3 antibody blocked the interaction between LAG-3 and MHC class II molecules on Daudi cells with an IC50 of 5.5 nM, compared to a human IgG4 isotype control.

LAG-3 Stimulation of Cytokine Release In Vitro in the Absence of T Cell Receptor Engagement

Anti-LAG-3 antibody is not expected to stimulate detectable cytokine responses without specific stimulation by the T cell receptor. Anti-LAG-3 antibody was immobilized and highly crosslinked by air-drying on a tissue culture plate and tested for its ability to stimulate cytokine production using a method derived from Stebbings R., et al. (J Immunol. 2007 179(5):3325-3331). No IL-2 or IFN-γ production was induced by anti-LAG-3 antibody or control IgG in the absence of staphylococcal enterotoxin B (SEB) stimulation of whole blood.

Example 4: Patient Selection Based on PD-L1/CD8/IFN-γ Status

For each of several types of cancer, samples from multiple patients were tested for PD-L1/CD8/IFN-γ status. Each sample was classified as: triple-negative for PD-L1/CD8/IFN-γ, single or double positive for these markers, or triple-positive for these markers. FIG. 11 shows that in this experiment, within a population of patients, the following types of cancer are frequently triple-positive for PD-L1/CD8/IFN-γ: Lung cancer (squamous), lung cancer (adenocarcinoma), head and neck cancer, cervical cancer (squamous), stomach cancer, thyroid cancer, melanoma, and nasopharyngeal cancer. Patients having these types of cancer are good candidates for therapy with anti PD-1 antibodies in combination therapies as described herein, e.g., anti-LAG-3 antibodies. The likelihood of successful treatment can be further boosted by determining which patients are triple-positive for PD-L1/CD8/IFN-γ, and treating the triple-positive patients with anti-PD-1 or anti-PD-L1 antibodies and combination therapies as described herein, e.g., anti-LAG-3 antibodies.

FIG. 12 shows that within a population of patients, the following types of cancer are rarely triple positive for PD-L1/CD8/IFN-γ: ER+ breast cancer and pancreatic cancer. Notably, even in cancers that are generally not positive for PD-L1/CD8/IFN-γ, one can increase the likelihood of successful treatment by determining which patients are triple-positive for PD-L1/CD8/IFN-γ, and treating the triple-positive patients with anti-PD-1 or anti-PD-L1 antibodies and combination therapies as described herein, e.g., anti-LAG-3 antibodies.

FIG. 13 shows the proportion of breast cancer patients that are triple positive for PDL1/CD8/IFN-γ. Considering breast cancer in general, the proportion of triple-positives is somewhat low. However, when one focuses only on IM-TN breast cancer, it can be seen that a much larger percentage of patients is triple positive for PD-L1/CD8/IFN-γ. IM-TN breast cancer is particularly difficult to treat with conventional therapies. The discovery that IM-TN breast cancer is often triple-positive for PD-L1/CD8/IFN-γ opens up new avenues of therapy for this cancer with anti-PD-1 or anti-PD-L1 antibodies and combination therapies as described herein, e.g., anti-LAG-3 antibodies.

FIG. 14 shows the proportion of colon cancer patients that are triple positive for PD-L1/CD8/IFN-γ. Considering colon cancer in general, the proportion of triple-positive is somewhat low. However, when one focuses only on MSI-high (high microsatellite instability) breast cancer, it can be seen that a much larger percentage of patients is triple positive for PD-L1/CD8/IFN-γ. MSI levels can be assayed using, e.g., commercially available PCR-based methods.

Gastric cancer samples were tested for levels of PD-L1/CD8/IFN-γ (data not shown). It was found that in MSI-high or EBV+ gastric cancers, about 49% were positive for PD-L1, and a high proportion of the PD-L-positive cells were triple positive for PD-L1/CD8/IFN-γ. It was also found that a proportion of PD-L-positive cells and PD-L1/CD8/IFN-γ positive cells were also positive for PIK3CA. This finding suggests that these cancers may be treated with a PD-1 or an anti-PD-L1 antibody, e.g., in combination with an anti-LAG-3 antibody, optionally in combination with a PIK3 therapeutic.

MSI-high CRC samples were tested for a combination of markers (data not shown). It was found that in MSI-high CRC samples, a high proportion of the PD-L1/CD8/IFN-γ samples are also positive for LAG-3, PD-1 (also called PDCD1), RNF43, and BRAF. This finding suggests that these cancers may be treated with a LAG-3 antibody, optionally in combination with a therapeutic that targets one or more of PD-1, PD-L1, PDCD1, RNF43, and BRAF.

Squamous cell lung cancers were tested for a combination of markers (data not shown). It was found that in squamous cell lung cancer samples, a high proportion of the PD-L1/CD8/IFN-γ samples are also positive for LAG-3. This finding suggests that these cancers may be treated with a LAG-3 antibody, optionally in combination with a therapeutic that targets PD-1 or PD-L1, e.g., an anti-PD-1 antibody or an anti-PD-L1 antibody.

Papillary thyroid cancers were tested for a combination of markers including the BRAF V600E mutation (data not shown). It was found that a high proportion of thyroid cancer samples that are positive for PD-L1 are also positive for BRAF V600E. This finding suggests that these cancers may be treated with an anti-PD-1 antibody or an anti-PD-L1 antibody, e.g., in combination with an anti-LAG-3 antibody, optionally in combination with a therapeutic that targets BRAF.

Example 5: Patient Selection Based on PD-L1 Status

To enable broad examination of cancer indications for immunomodulator (e.g., LAG-3 alone or in combination with PD1/PD-L1) based therapies, PD-L1 expression was evaluated at both the protein and mRNA levels in human cancers including both lung and hepatic tumors.

PD-L1 protein expression was evaluated in a set of formalin-fixed paraffin-embedded non-small cell lung (NSCLC) adenocarcinoma (ACA), NSCLC squamous cell carcinoma (SCC), and hepatocellular carcinoma (HCC) tumors by immunohistochemistry (IHC). PD-L1 expression was scored semi-quantitatively by a manual histo-score (H-score) methodology based on staining intensity and percentage of positive tumor cells. In our IHC analysis, PD-L1 positivity (PD-L1+) was defined as an H-score ≥20. In parallel, PD-L1 mRNA expression data was examined from The Cancer Genome Atlas (TCGA) in these same indications (503 NSCLC ACA, 489 NSCLC SCC, and 191 HCC) and analyzed by comparing the expression in matched normal tissues from TCGA.

With RNAseq analysis, data was calculated as log 2 (RPKM+0.1) after RSEM normalization, utilizing OmicSoft RNASeq pipelines across TCGA tumor indications. The expression of PD-L1 is elevated in NSCLC ACA and SCC, relative to that in HCC. By overlaying the distributions and comparing the expression levels across all indications in TCGA, we ranked overexpression profiles for PD-L1 and found the TCGA HCC cohort to have much reduced PD-L1 mRNA levels, with a median level of −0.8 compared to 1.3 for ACA and 1.5 for SCC, which amounts to more than a 2-fold change of median level expression. With RNAseq, our analysis defines 50% of NSCLC adenocarcinoma, 54% of NSCLC squamous cell carcinoma, and 6% of HCC as high expressers for PD-L1.

Tumor cell PD-L1 protein expression was measured in 45 lung adenocarcinoma (ACA) samples, 47 lung squamous cell carcinoma (SCC) samples, and 36 hepatocellular carcinoma (HCC) samples. 16/45 (35.6%) lung ACA, 21/47 (44.7%) lung SCC were PD-L1 positive. In contrast, PD-L1 positivity was seen in only 2/36 (5.6%) HCC samples.

In summary, with IHC and RNAseq analysis in large and independent human NSCLC and HCC sample sets, PD-L1 expression was found to be more enriched in NSCLC than in HCC. Within NSCLC, there are comparable findings between adenocarcinoma and squamous cell carcinomas. Importantly, amongst the large number of samples (128 for IHC and 1183 for RNAseq) in the 3 indications, very good concordance is observed between protein- and mRNA-based analyses. This finding thus establishes the basis for large scale mRNA-based data mining in TCGA for indications and patient segments that may be enriched for responses to immunomodulator (e.g., PD-1/PD-L1, e.g., in combination with LAG-3) based immune therapies.
